INTRODUCTION INTRAC-305
INTRODUCING THE INTRAC-305
The INTRAC-305 INtelligent TRacking Antenna Controller is a microprocessor based controller for tracking any nominally geostationary satellite including those at low elevation or with high angles of inclination. It has been designed as a direct physical replacement for the Andrew APC300 Steptrack Controller. For information on replacing an Andrew APC300 with the INTRAC-305 see section 6 - Installation.
The INTRAC-305 builds a model of the satellite’s orbit using a mathematical algorithm. To build the orbit model the INTRAC makes measurements by perturbing the antenna pointing angle very slightly and monitoring the change in received beacon signal strength. These small movements enable the INTRAC to estimate the position of the satellite and this estimate is used by the modelling algorithm.
The system always tracks the satellite from the orbit model. The small movements of antenna pointing are only used to maintain and update the model.
By using the model to point the antenna the INTRAC system ensures that the antenna is always pointed accurately at the satellite. This is in contrast to Step Track systems where the antenna spends most of the time not actually pointing directly at the satellite.
The regular measurements made by the INTRAC ensure that changes in the apparent orbit, due to station keeping manoeuvres or other causes, are identified. The model is modified and refined to incorporate these changes and accurate tracking is automatically maintained. The INTRAC will automatically increase the measuring rate if necessary in order to obtain sufficient information on the changing orbit.
As the INTRAC tracks using its orbit model it will continue to track the satellite if the tracking signal is degraded or lost. The satellite position may be accurately predicted from the model for up to 72hrs without a tracking signal.
The INTRAC system provides this exceptional tracking performance and robustness for satellites with any inclination, at any look angle, even in the presence of severe beacon signal degradation entirely automatically. No operator intervention or parameter setting is required when conditions or satellites are changed.

INTRAC-305 INTRODUCTION
A Typical System
The antenna position resolvers provide direction information to the INTRAC. The IBR-L (beacon receiver) provides tracking signal strength. (A signal strength derived dc voltage from an external receiver may be used in place of the Advantech AMT IBR-L)
The Motor Drive Cabinet receives the antenna drive commands from the INTRAC and drives the azimuth, elevation and polarisation (option) motors and brake assemblies.
Limit switches on the antenna prevent it from being moved beyond mechanically defined positions.
The INTRAC-305 may be controlled from its front panel or from an optional PC based Remote Control and Monitoring Terminal.
Retro Fitting Existing Step Track or Program Track installations may be
updated to INTRAC systems. Advantech AMT Ltd. have considerable experience of retro fitting INTRAC systems.

IQUICK START GUIDE INTRAC-305
A suggested quick start procedure is given below:
1/ Before modifying system make a note the antenna pointing angles from the old tracking
system. 2/ Perform any recommended resolver mounting bracket modifications. 3/ Connect INTRAC-305 in place of Andrew APC300 and check that the Fitted Options
(Home>Function>System Setup>Fitted Options) (Manual page 39) are set correctly. Note
that the resolvers used with the APC300 system were normally x2 resolvers which would
require the x2 setting in the fitted options. 4/ Select Station Coordinates (Home>Function>System Setup>Station Coordinates) and
ensure that latitude is in correct hemisphere (North or South). You only need to enter the
correct station co-ordinates if you intend to use IESS-412 or Norad ephemeris data. 5/ Select Date and Time (Home>Function>System Setup>Date & Time) and enter the correct
time and date (in UT (GMT)). This is only strictly necessary if you intend to use IESS-412 or
Norad ephemeris data, but most users prefer to set the time correctly anyway. 6/ Select beamwidth (Home>Function>System Setup>Az & El Beamwidth) and set the receive
3 dB beamwidths of your antenna. 7/ Now ensure drive direction feedback is correct.
Select Manual on INTRAC . (Home>New Mode>Manual/Stow) Note displayed Az angle.
Command drive Right. Check if displayed angle increases or decreases.
Command drive left. Check if displayed angle increase or decreases.
Continue driving left until displayed angle has returned to the previously noted angle.
The angle should have increased while driving right and decreased while driving left. If it did
the opposite then the resolver sense is not correct and will need correcting. By bringing the
antenna back to the original displayed angle we have maintained the angle reference.
Note the displayed Elevation angle and repeat the operation for Elevation. Commanding Up
should give an increasing angle, Down a decreasing angle. If you found the opposite then
you will need to change the elevation resolver sense. Make sure you return the antenna to
the same elevation position (reading). 8/ If either resolver senses required changing then Select Fine Tune (Home>Function>System
Setup>Fine Tune) and change the required senses on the first screen. Then press EN to
continue and adjust the fine tune offsets so that the angle display reads the correct angles (
the ones you noted in step 1). 9/ Now check that Manual drive drives the angles in the expected direction. At this point you
can also check that the physical direction on motion of the antenna is also correct, but this
will be correct if the original installation was correct. 10/ Connect the beacon signal.
If an IBR-L is fitted and an L-band beacon is available connect this to the RF input on the
rear panel of the INTRAC. Select the correct frequency and check that a valid beacon level
is displayed. Manually peak the antenna to maximize the beacon level and check that the
beacon does not overload (24.9 dB displayed).
Page viii INTRAC-305 MANUAL - ISSUE 3.2 © 2011 Advantech Wireless
INTRAC-305 QUICK START GUIDE
If an IBR-L is not fitted then provide a voltage signal to the beacon 1 input. You will need to adjust the potentiometers (See manual page 76) to set the gain and offset to the correct values. Manually peak the antenna to maximize the beacon level and check that the
beacon does not overload (24.9 dB displayed). 11/ Set any other parameters, such as Soft Limits. 12/ Select Auto-New Model (Home>New Mode>Auto New Model) and press enter. Monitor
system over 24 hours and check that system is maintaining track with displayed mode
“Learning”. Soon after the 24 hour learning period the mode should change to “Tracking”,
indicating that the system has successfully computed a full INTRAC model.

SPECIFICATION & OPTIONS INTRAC-305
OPTIONS A number of options are available for the INTRAC-305.
The options are described in the following pages. Some of
these options require changes to the firmware or hardware and some are only available when ordered at the time of initial order.
Serial Interfaces only need a change to switch and / or
connector positions within the INTRAC.
Voltage The power supply unit (or units for Dual Redundant PSU
option) of the INTRAC-305 auto switch for nominal mains voltages of 110Vac or 220Vac.
Tracking Signal The INTRAC-305 can be supplied with an integral L-band
beacon receiver (IBRL). Alternatively a voltage, from an external receiver, which varies directly with the received signal strength in dB may be used. The IBRL option should be specified at time of initial order.
Serial Interfaces There are three communication ports on the INTRAC-305,
“Remote Port”, “Test Port 1” and “Test Port 2”. The Remote
Port is configured for RS232/RS423. Test Ports 1& 2 can be independently configured as either RS423 or RS422.
This involves connecting the rear panel connectors to the
appropriate connectors on the main board and setting the option links as shown below.
Polarisation If the antenna has motorised polarisation the INTRAC can be
user configured to control the polarisation angle. Polarisation uses the standard Andrew polarisation resolver.
Note The standard version of the INTRAC-305 is firmware
configured for a Pol resolver geared 1:1 to the polarisation tube. Firmware for a Pol resolver geared 2:1 to the polarisation tube is available if required. Note this is a

INTRAC-305 SPECIFICATION & OPTIONS
firmware change and required the EPROM on the interface
card to be changed.
Mount Type Two types of antenna mount may be used with the INTRAC.
An Az/El mount or a Polar mount. The appropriate one is
selected in “Fitted Options” as AZ/El or Hr-Ang/Declination.
Resolver Type The INTRAC-305 is intended for use with standard Andrew
resolvers, either x2 or x1 versions. Normally the INTRAC-305
is to replace an Andrew APC300 and the antenna will have
been fitted with x2 resolvers. Refer to the earlier specification
section. This is a user configuration option.
Stow Option There is provision in the INTRAC-305 configuration for Az/El
preliminary and final stow positions to be set. The “Stow” command causes the antenna to be driven to the
preliminary position in both axes. Once at this position the
antenna is driven to the final position. The “Unstow” command causes the pin(s) to be removed
(where appropriate) and the antenna driven to the preliminary
position. The preliminary and/or final positions can be set to “not-
used” for one or both axes.
Dual Redundant PSU The INTRAC-305 can be supplied with dual redundant power
supplies. In this option the single PSU is replaced by two indepenent PSUs and associated combining hardware. Independent switched power inlets are provided and the front panel power switch is replaced by status LEDs. The INTRAC-305 will operate normally when either or both PSUs are operational. This option must be requiested at time of initial order

required satellite by either the Goto Position or Goto Satellite
commands or manually. Alternatively the Az & El co-
ordinates can be entered on this screen. Using Menu Key 6 (Next Field) and the numeric keys the
satellite's position and beacon frequency may be entered. The search box size and the antenna dwell time are also
entered in the same manner. The box size parameters are either side of the nominal angle
thus entering 2 will cause a 4 scan. The dwell time is the time that the antenna will remain at each
step. It is the lock time of the beacon receiver. For the IBR-L
(The Signal Processors supplied Integrated Beacon Receiver)
the default dwell time of 25 seconds is correct. Once all the co-ordinates are set pressing ENTER will start
the search. The antenna will drive to the nearest corner of
the search box before commencing the search pattern.

Description This facility does not have a screen of its own. It is a function
enabled by a menu key on the New Mode menu.
Auto New Model is used when it is required to track a new
satellite. It causes the INTRAC to clear the existing model (if there is one) and start to build a new model of the orbit of the satellite whose beacon signal it is receiving.
Thus before pressing the Auto New Model key the antenna
must be peaked on the required satellite’s main transmission
lobe. The peaking may be done in manual mode or automatically using Search Mode.
On pressing Auto New Model the INTRAC will enter Learning
mode. After 24hrs of learning the orbit and building the model the INTRAC will enter Tracking mode.

FINE TUNE - Offsets
Path See “FINE TUNE - Sense” on previous page. Description This menu allows an offset to be inserted between the “angle”
from the resolver and the displayed angle in order to calibrate the system for any difference between the actual antenna angle and the resolver angle.
The actual pointing angles of the antenna are accurately
established and the displayed angles are set to those angles using this facility.
Azimuth & Elevation or Polarisation are selected using menu
key 5.
The setting of the offset is done using the manual drive keys.
For Az & El the right and left keys offset the Az and the upper and lower keys offset the El. For Pol the right and left keys are used.
The angles displayed in the upper section of the menu screen
change in real time. Menu Key 6 may be used together with
the direction key to increase the rate of change. The actual amount of offset is not displayed. The offset can be returned to zero for any angle by pressing
the opposite keys at the same time. Care should be taken to release both keys at the same time
otherwise another offset will be inserted. Note This should only be carried out at commissioning or on the

MODELS - ENTER Description IESS-412 & NORAD ephemeris data can be loaded into the
INTRAC-305. This data is primarily for Program Track use.
HOWEVER the INTRAC-305 can use this data to generate an
ORBIT MODEL for the satellite. The advantage of this is that
the model is available immediately rather than after the 24hrs
it would take if the INTRAC had to learn the orbit. The
INTRAC is then immediately immune to long beacon outage
or power failures. The INTRAC will accept the ephemeris data two days either
side of the data’s actual validity period. The SGP/SDP modelling algorithms for the NORAD data will
give slightly different pointing results for a given set of data.
Except that the SGP4/8 algorithms are for Near Earth orbits
and SDP4/8 are for Deep Space orbits. (Geostationary Orbits
are SDP). The INTRAC will not allow a model to be made
using the wrong type of orbit algorithm. It is assumed that the user will know which NORAD algorithm
applies for the data being used. Menu Key 6 (Next Field) steps the selecting highlight through

Description Once the INTRAC-305 has built an orbit model it can track
the satellite with no tracking signal for 72hrs. After this time if
there is still no signal the INTRAC deems the model to be
expired and ceases to track. In such a situation the INTRAC can fall back into Program
Track mode using the “Reserve Model”. The “Reserve Model” requires that valid IESS-412 or NORAD
data be loaded and that the required reserve model is
selected. In this menu the required reserve model, IESS-412 or

OPERATION INTRAC-305
NORMAL OPERATION Continuing Tracking With the INTRAC-305 operating normally it will be in Tracking
Mode and will require no operator input. Should it become necessary to move the antenna off satellite
for some reason, such as to stow it because of wind, all that
is required to resume tracking is to select Auto Continue.
(after the antenna has been unstowed)
To Track a new Satellite Set the Beacon Frequency. Set the Polarisation angle if motorised Pol fitted. Point the antenna at the required satellite using Manual
control, Goto Position or Goto Satellite. Peak the antenna on the beacon signal using Manual control
or Search. When the antenna is peaked on the beacon signal cause the
INTRAC to enter Learning Mode by selecting Auto New
Model. After 24 hours of learning the INTRAC will automatically enter
Tracking Mode. Note If Auto Continue is selected instead of Auto New Model and
the previous model has not been cleared the antenna will
drive back to the previous satellite and continue tracking it.
If the beacon signal is lost the INTRAC will enter Predicting
Mode. It will then track the satellite by predicting from the
model for a period of time depending on how long it has been
learning. If Tracking Mode had been achieved before the
signal is lost the INTRAC will track in Predicting Mode for up
to 72 hours after which time it will deem the model to no
longer be accurate enough. When the beacon signal returns, if the INTRAC is still in
Predicting Mode, Tracking Mode will be resumed. If the
INTRAC has entered Standby, due to the period without
signal being too long, Learning Mode will have to be invoked
from the front panel.

INTRAC-305 ALARMS & ERRORS
4. ALARMS & ERRORS
The INTRAC-305 has two type of alarm condition. Primary
Alarms and Secondary Alarms. The system will go into Standby mode if a Primary Alarm is triggered. Secondary Alarms leave the INTRAC in its current mode.
PRIMARY ALARMS A Primary Alarm becomes active if one (or more) of the
following conditions arise :-
Antenna movement limit switch activated. Software limit tripped. Emergency Stop button operated. Interlock switch activated. Motor drive failure. (Drive Fail Alarm) Antenna moves in wrong direction. (Drive Fail Alarm) Hardware (processor) fault. Antenna driven within 1.4 of 0 Az in the Northern
Hemisphere or within 1.4 of 180 Az in Southern Hemisphere (Drive Fail Alarm).
Resolver fault. (Synchro alarm) (apparent position
change of more than 1.4 in1/64 second).
Drive Fail Alarm The Drive Fail Alarm encompasses a number of other alarms.
If there has been no change in the least significant bit (LSB) of the resolver output within 10 seconds of drive being activated. If either Az or El axis drive more than 1.4 in the wrong direction. If the antenna is driven within 1.4 of North (Azimuth 0) {or 1.4 of South (Az 180) Southern
Hemisphere}. The Drive Fail Alarm is not activated in Manual (P) Mode. If a drive time-out occurs the INTRAC enters Standby Mode.
This prevents the drive motors being damaged by continually
re-starting. When any Primary Alarm becomes active the red “System
Alarm” indicator on the INTRAC front panel illuminates and
the system enters Standby Mode. The actual alarm which
has occurred can then be viewed on the screen by pressing
Menu Key 5 (Show Alarms) in the Home menu.
© 2011 Advantech Wireless INTRAC-305 MANUAL - Issue 3.2 Page 49
ALARMS & ERRORS INTRAC-305
SECONDARY ALARMS There are three Secondary Alarms :-
Unable to Predict Alarm. Beacon Alarm. Servo Alarm.
Unable to Predict This alarm is raised when the INTRAC has not enough
confidence in the orbit model to be able to predict the satellites position. e.g. during the early part of learning a new model or after there had been no beacon signal for more than 72 hours.
Beacon Alarm The Beacon Alarm is raised when the signal strength does
not vary during step cycles or when beacon lock is lost.
Servo Alarm The Servo Alarm is raised when the INTRAC fails to detect
the expected amount of antenna movement during a step cycle. This can be caused by the servo performance not
corresponding to the routine’s model of the antenna drive
characteristics. The INTRAC reacts by repeating the step cycle with a larger drive demand.
Secondary Alarms do not, necessarily, mean that there is a
system fault nor do they illuminate the System Alarm indicator. The occurrence of a secondary alarm may be checked by selecting Show Alarms in the Home menu.
ALARM OUTPUTS Three sets of changeover relay contact outputs are available
on a 25-way D-type connector on the INTRAC rear panel. There is one relay for a Primary Alarm, one for a Secondary Alarm and the third indicates that the beacon signal has fallen below the user set beacon threshold.
RECOVERING FROM ALARMS All Primary Alarms, except the Hardware Alarm in Auto Mode,
cause the unit to be put into Standby Mode. Recovery from Drive Fail, Synchro and Hardware (other than when in Auto Mode) Alarm conditions are cleared by pressing any Mode selection key (eg Standby). Soft Limit and hard limit alarms can only be cleared by driving back from the limit using Manual Mode. Emergency Stop and Interlock alarms can only be cleared by removing the cause of the alarm.
If a Hardware Alarm occurs when the INTRAC is in Auto
Mode the unit will perform a processor reset and then enter learning mode to re-learn the orbit model.

INTRAC-305 ALARMS & ERRORS
POWER FAILURE The INTRAC incorporates non-volatile memory and a battery
backed real time clock. The onset of a power failure is
detected and the current mode is stored before the processor
ceases to operate. When power is restored the INTRAC
performs an automatic recovery as below :­ If the unit was in Auto (Tracking) Mode at the time of the
power failure and no Primary Alarms have become active the
unit will resume tracking. The antenna will be moved (if
necessary) to the current satellite position based on the orbit
model and the real time clock. If the unit was in Auto (Learning) Mode it will resume in that
mode. However whether it continues learning or re-starts to
learn depends on the ratio of the completed learning time to
the period without power. (i.e. how dependable the learnt
orbit will now be) If the INTRAC was in any other Mode or if a Primary Alarm
had occurred the unit will power up in Standby Mode with a
power-up alarm.
ERRORS Errors are user errors and involve the entry of non valid data.
Where data is entered outside the allowable limits for that
data such as setting the beacon frequency outside the range
of the selected band. The entered data is changed to the limit
nearest to the entered value and marked with an asterisk (*).
On the bottom of the screen the message :-
“ENTRY ERROR!, limits forced =*” is displayed. The forced limit data may be accepted by re-pressing the
ENTER key or the correct value keyed in.
IESS-412 DATA Where IESS-412 data is entered with the incorrect 170hr
checksum the checksum is corrected by INTRAC in the same manner as above. However it is up to the user to ascertain that it was the checksum which was wrong and not that wrong value data was entered.

INTRAC-305 TECHNICAL DESCRIPTION
5. TECHNICAL DESCRIPTION
This section looks at and explains the Operational Modes and
Functions of the INTRAC-305 and at the tracking algorithm that makes the INTRAC-305 one of the most accurate tracking antenna controllers available.
The INTRAC-305 achieves its very high accuracy satellite
tracking by building a model of the satellite’s orbit and then by using that orbit model to direct the antenna.
The algorithm used to build the orbital model has been
continually developed and enhanced by Advantech AMT Limited since 1983.
The tracking accuracy is typically similar to that achieved by a
monopulse system and can, under some conditions, be better than that achieved by a monopulse system.
THE TRACKING ALGORITHM During initial acquisition the INTRAC algorithm tracks the
satellite using a third order (for each axis) unbiased tracking filter. This algorithm dynamically adjusts the period between the step cycles to match the perceived orbit inclination and received beacon signal level fluctuations and noise level. During this initial period the tracking accuracy is only very slightly lower than the full long term INTRAC tracking accuracy.
The most significant difference during the learning period (first
24hrs) is not the accuracy of tracking but the time for which the system can predict in the event of loss of the beacon signal. This can be overcome by using Intelsat IESS-412 or NORAD data to establish an initial INTRAC model so that the full prediction ability is available from the start. This model is then modified and optimised by the INTRAC algorithm in the same manner as it would continuously update a model it had “learnt”.
The key to deriving a reliable and accurate orbital model is the
ability to derive accurate estimates of the many parameters involved in the model. Much specialised noise processing expertise and experience has been applied in the design of the INTRAC algorithm to ensure that INTRAC can build an accurate model and can maintain it even when the beacon signal is subject to severe fluctuations.
The INTRAC algorithm uses a robust pointing error estimator to obtain the raw satellite
position estimate, normally at 10 minute intervals. The raw satellite position estimate is filtered with a narrow noise-bandwidth tracking filter to produce the basic, multi parameter, orbital model. To correct short-term errors in the basic model resulting from modelling error, windage and satellite station keeping manoeuvres, the difference between

TECHNICAL DESCRIPTION INTRAC-305
the raw satellite position estimate and the orbital model is filtered with another tracking filter (known as the "relationship algorithm") capable of tracking and correcting transients. This is then combined with the basic model to form a reliable predictor that tracks mean windage, refraction and stationkeeping manoeuvres without error.
The INTRAC tracking filters are designed in such a way as to
enable the model to provide the required accurate pointing prediction at all times. Even when not verified by measurements, as for example occurs with loss of beacon, the tracking filters are capable of accurately predicting the satellite orbit for many days. Under INTRAC control, pointing is always controlled from the internal satellite orbit model. When a measurement cycle is performed it is always done as a perturbation with respect to current pointing. Thus, unlike conventional steptrack, INTRAC is always on track when a measurement cycle is performed. INTRAC never uses the measurement cycle for the purpose of directly bringing the beam on track. INTRAC simply performs one measurement cycle in each axis every 10 minutes in order to up-date the parameters used in the orbital model and for the rest of the time keeps the beam correctly pointed.
As a result of the combination of thermal noise, fade,
scintillation, random windage-induced platform-reference motion and other noise sources the beacon signal will, during a measurement cycle, contain noise additional to that directly attributable to the measurement cycle itself. Careful algorithm design ensures that this noise has zero mean value and has a value of standard deviation such that it is equivalent to thermal noise of a certain effective value of C/No. By special design of the measurement cycle the INTRAC system minimises this effective value of C/No in a way that is not possible with conventional steptrack methods. Furthermore the INTRAC measurement cycle design discriminates so effectively against the slow component of received beacon signal power fluctuation, caused for example by rain fades, that it almost completely suppresses errors caused by linear beacon ramps of all practicable slopes.
The INTRAC algorithm also incorporates adaptive
compensation for imperfections in the antenna drives. As a result its performance is largely unaffected by servo backlash, AC track motor drive rate and transportation rate (motor to axis rate) and coast because of the specific choice of perturbation pattern and the use of high resolution position transducers. The INTRAC servo algorithm dynamically calibrates the mechanical coast of the antenna and automatically compensates for it if it is within reasonable limits (less than 1/20 beamwidth).
Wind affects tracking in two ways. The antenna structure is
distorted by the wind load and this distortion shifts the beam pointing relative to the angle transducer reading. This
Page 54 INTRAC-305 MANUAL - Issue 3.2 © 2011 Advantech Wireless

INTRAC-305 TECHNICAL DESCRIPTION
component of beam shift is not visible to the position transducers. The mean of the reference shift is tracked by the INTRAC algorithm in a similar way to a stationkeeping manoeuvre.
The component of beam shift that is visible to the position
transducers is entirely tracked by INTRAC within a 10 MHz noise bandwidth. When the position transducers accurately reflect beam deflection in wind INTRAC continuously tracks this antenna deflection at 16 sec updates. To support tracking of visible wind-induced beam deflection between measurement cycles the INTRAC servo control algorithm maintains a short-term average of beam pointing. When deciding whether to update beam pointing INTRAC references this average rather than the current pointing. A further small deadband is also applied to suppress unnecessary hunting.
The INTRAC tracking filter distinguishes received beacon
signal power fluctuations, fades and noise from the mean component of windage-induced beam-pointing, orbit changes and beam refraction. The effect of the fluctuations, fades and noise on the INTRAC tracking filter is as if these were a zero mean position random noise source. The variance of these is brought within specification by tracking the position estimates with a narrow noise bandwidth tracking filter. The mean components of windage-induced beam-pointing, orbit changes and refraction are seen as transients to be tracked by the INTRAC relationship algorithm. The design of the relationship algorithm is a carefully evolved working compromise between transient performance and noise suppression which provides high accuracy tracking under all conditions likely to be encountered in practice.
THE MODES The INTRAC-305 has six major operational modes :­ Standby
© 2011 Advantech Wireless INTRAC-305 MANUAL - Issue 3.2 Page 55
TECHNICAL DESCRIPTION INTRAC-305
Auto - (tracking but includes learning & predicting) Manual Goto - (Goto Satellite, Goto Position & Search) Sleep - (alarm induced, not user selectable) Remote (transfers control to a remote terminal)
Standby Standby mode is a “no movement” mode, the antenna is not
driven (the brakes where fitted will be applied) but the pointing angles and beacon signal level are monitored and displayed.
External inputs to the INTRAC are also monitored and any
primary alarms which occur are indicated. Any primary or
secondary alarms will be displayed if “Show Alarms” is
selected. Standby mode is entered in one of three ways :­ selected by the operator a primary alarm occurs at the end of a Goto move or at the end of a search
Auto (normal operating mode) After pointing and peaking the antenna at the required satellite
Auto New Model should be selected. This will cause the
INTRAC to enter its period of learning the satellite’s orbit. The INTRAC performs cross scans to determine the satellite’s
position. These scans are performed at intervals (normally ten
minutes but more frequently if INTRAC deems necessary) and
the pointing parameters used to build the orbital model. When
carrying out a cross scan the antenna describes a small cross
(normally +/- 5% of the antenna’s 3dB beamwidth) in the sky to
determine the satellite position estimate. After 24hrs the INTRAC has built the full orbital model.
However during the building process the INTRAC maintained a
simple orbit model for the satellite which allowed INTRAC to
track with very nearly the same accuracy as its long term
accuracy.
Once the model is complete the INTRAC enters Tracking
Mode. The model is used to point the antenna and because of
Page 56 INTRAC-305 MANUAL - Issue 3.2 © 2011 Advantech Wireless

INTRAC-305 TECHNICAL DESCRIPTION
the high accuracy of the model the tracking is within 0.05dB of peak signal tracking.
In Tracking Mode the INTRAC continuously updates the model
by making small perturbations of the antenna and incorporating the resultant data into the model. During periods when the
satellite’s orbit is changing because of station keeping
manoeuvres the INTRAC may increase the frequency of the perturbations.
If the beacon receiver stops providing a useful signal* the
INTRAC will enter “Predicting” sub mode. In this mode the INTRAC will continue to point the antenna according to the
model but will not update the model. Once “Tracking Mode” has been achieved “predicting” can continue for 72hrs. If the
beacon receiver returns to providing a useful signal* within this period the INTRAC returns to updating the model. If, after 72hrs, the beacon is still not producing a useful signal* the model is deemed to have expired. If this occurs the INTRAC
can fall back on the “Reserve Model” which is a Program Track
using either IESS-412 or NORAD data. (see Reserve Model ­page 48)
* useful signal A useful signal is defined as one that varies sensibly during
antenna movements, is neither over or under range and the beacon receiver is in lock.
Manual Manual Mode allows the operator to drive the antenna using
the Manual Control keys on the INTRAC front panel. It is normally only used for small movements of the antenna such as peaking when the position of the satellite is known with close accuracy.
For larger antenna movements one of the Goto modes is faster
and where the satellite’s position is only roughly known search
is employed to peak the antenna.
There are two Manual Modes. Manual (P) Mode is manual
control from the front panel. Manual (A) Mode is manual control from the Remote Terminal. (see section 9). The antenna can be driven through North (Azimuth 0), in the Northern Hemisphere, or South (Az 180), in the Southern Hemisphere, only in Manual (P) Mode.
Goto There are three Goto sub modes. Goto Position and Goto
Satellite provide a convenient method of driving the antenna to a specific position. Search mode is the automatic scanning of an area of sky for a satellite.
Goto Position In this mode the operator enters the co-ordinates and beacon
frequency of the required satellite and presses the enter key. The entered co-ordinates are checked for validity (i.e. are they
© 2011 Advantech Wireless INTRAC-305 MANUAL - Issue 3.2 Page 57
TECHNICAL DESCRIPTION INTRAC-305
within the soft limits?). If they are invalid the INTRAC sets the
maximum possible angle(s) in the required direction and
prompts the operator for action. If the co-ordinates are valid
the INTRAC drives the antenna to those co-ordinates and
enters Standby. The antenna can then be peaked using
manual mode or search mode (see below) before selecting
Auto New Model. Note If Auto Continue is selected at the end of Goto and there is a
model in existence the INTRAC will continue to track using that
model. To commence learning a new orbit either Auto New
Model should be selected or any existing model cleared before
selecting Auto Continue.
Goto Satellite This mode allows one of the previously programmed satellites
(up to 40 can be programmed) to be selected by number and
its position driven to. Using the “Edit Satellite” sub menu of the
Goto Satellite menu a new satellite can be added or an existing
one edited. Having selected the required satellite pressing the
enter key causes the antenna to be driven to that satellite. The
INTRAC enters Standby when the antenna is at the satellite’s
position. Antenna position peaking can then be carried out
manually or in search mode (see below). To commence
tracking this new satellite select Auto New Model or if there is
no existing model Auto Continue may be selected. (see Note
above)
Search Search Mode conducts a search of the sky based on
parameters entered in this menu. When the menu is entered
the displayed parameters are those of the current antenna
pointing. e.g. the parameters from a Goto move. If these
parameters are not those required they may be edited in this
menu. (see page 21) The search box size angles are plus and minus on the nominal
angle. Thus entering 2 by 2 would cause a search box of 4
square. The search begins in the nearest corner of the defined box to
the antenna’s current pointing. The search pattern is a “toast
rack” or “serpent shape. The scanning comprises full scans in
elevation for each move in azimuth. The azimuth move is
equal to the 3dB beamwidth of the antenna commencing 1/2 of
the 3dB beamwidth in from the edge of the box. The position of the highest beacon signal strength during these
scans is recorded. At the end of the “serpentine” search the
antenna is driven to the point of highest signal strength found
during those scans and phase two of the search is
commenced. This is the peaking phase and causes the antenna to search a
smaller area of sky around the point of highest signal strength
for the peak level. Again the position of the highest signal
Page 58 INTRAC-305 MANUAL - Issue 3.2 © 2011 Advantech Wireless
5
INTRAC-305 TECHNICAL DESCRIPTION
strength is recorded and at the end of this phase the antenna is driven to that position and the INTRAC enters Standby.
At this point the peak may be confirmed manually and/or
learning mode entered by selecting Auto New Model.
Remote Remote Mode transfers control of the INTRAC to a remote
terminal.
It is selected with Menu Key 6 (Select Remote) from the Home
menu. Once in Remote Mode only four functions are available from the INTRAC front panel. The emergency stop switch will inhibit the antenna drive as normal, the alarms can be displayed, Standby Mode can be entered and control can be returned to the front panel again with Menu Key 6 (Select Local).
USING IESS-412 OR NORAD DATA The INTRAC-305 can make use of Intelsat IESS-412 11-
parameter or NORAD ephemeris information in two ways.
1. The information can be used by the INTRAC to generate an INTRAC model of the satellites orbit.
This model is then be used by the INTRAC as it would
use a model it had learnt itself. This means that there is not the need for the 24hr learning period. The model is then updated as any INTRAC model would be.
2. The INTRAC can
be commanded to Program Track using positions calculated from the ephemeris data.
The IESS-412 and NORAD data sets can be entered either
manually from the INTRAC front panel or from a PC. A stand alone program is available for loading the data file from a PC. This program can be used alone or in conjunction with the Remote Control Terminal RCM-4.
A description of this program is given the appendices.
The IESS-412 data The IESS-412 data set comprises 21 fields of data :- IESS Epoch Year range: 80 to 99 (20th century)
00 to 79 (21st century) IESS Epoch Month range: 1 to 12 IESS Epoch Day range: 1 to 31 IESS Epoch Hour range: 0 to 32 IESS Epoch Minute range: 0 to 59 IESS Epoch Second range: 0 to 59

input on the Function - System Setup - Station Coordinates menu screen.
The IESS Epoch defines the time instant at the start of the
period of the IESS data. The IESS Minutes Interval defines the period in minutes between pointing updates in Program Track mode. The IESS Days Validity (normally 7) defines the period of validity of the data. The INTRAC will accept and use the data two days either side of the validity period.
The parameters IESS Sat (LM0, LM1, LM2, LONC, LONC1,
LONS, LONS1, LATC, LATC1, LATS, LATS1) are the IESS­412 11-element ephemeris. The parameters IESS Sat (LONG170, LAT170) are the IESS-412 11-element ephemeris 170hr parity check.
Note The data ranges shown above as +/- 9.99 actually accept more
than two places of decimals.
Note The LMO value is given in the range -180 to +180. The
INTRAC-305 cannot accept negative values for this field from the front panel. (It can accept them from the RCM-4). It is therefore necessary to add 360 to the supplied value if it is

NORAD data The NORAD ephemeris data consists of a string of 166
characters. The first 160 characters are split into two “Card Element Sets” of 80 characters each. The next two characters
(161 & 162) comprise the Minutes Interval and characters 163 & 164 comprise the Period of Validity of the ephemeris. The final two characters (165 & 166) are the check sum.
There are ten blocks of orbital element parameters contained
in the NORAD ephemeris character string :-

RAPID MODEL GENERATION The INTRAC-305 can use the IESS-412 or NORAD data to build the satellite’s orbit model instead of having to learn the
orbit over a 24hr period.
The IESS-412 data is selected for the Rapid Model Generation
in the Models menu and ENTER pressed. The orbit model is calculated and the INTRAC enters Tracking Mode.
For the NORAD data there are five choices of NORAD
algorithm. These are SGP, SGP4, SGP8, SDP4 & SDP8 and each gives a slightly different Az/El pointing for the same NORAD data.
SGP the original NORAD algorithm SGP4 applies to Near Earth Orbits SGP8 applies to Near Earth Orbits SDP4 applies to Deep Space Orbits SDP8 applies to Deep Space Orbits
Orbits are differentiated by their period. Those of less than 225
minutes are Near Earth Orbits and those of more then 225 minutes are Deep Space Orbits. Geostationary satellites are in Deep Space Orbit.
It is assumed that the user know which algorithm applies to the
data to be used. However INTRAC will not allow a Near Earth Orbit algorithm to be used with Deep Space Orbit data and vice-versa.

TECHNICAL DESCRIPTION INTRAC-305
The Basic algorithm available in the Rapid Model Generation
table is not of NORAD origin. It has none of the embellishments found in the NORAD routines and is meant for test purposes only.
Once the orbital model has been built using the ephemeris
data the INTRAC tracks the satellite from it and updates and improves it over the following hours and days.
PROGRAM TRACK The IESS-412 and NORAD data can also be used by INTRAC
to calculate the satellite’s path which is then used for a simple Program Track operation.
The selections available in Models - program Track are the
same as are available in Rapid Model Generate. On selecting the required algorithm and pressing ENTER the INTRAC enters Program Track mode.
Program Track is an open loop method of tracking and as such
is unable to correct for any transducer errors or distortions to the antenna caused by wind.
RESERVE MODEL Once the orbital model has been built the INTRAC tracks the
satellite extremely accurately by continuously monitoring the
satellite’s position and updating the model. When the beacon
signal is not present INTRAC can still track accurately by
predicting the satellite’s position from the model. However if
the beacon signal is lost for more than 72hrs INTRAC deems the model to be no longer valid. In such a situation INTRAC can fall back to a Reserve Model. This is a Program Track model built from either the IESS-412 or the NORAD data. The selection is made in Models - Reserve Model. Assuming the appropriated data has been loaded and is valid INTRAC will automatically fall back to this model when it can no longer predict accurately.
CLEAR MODELS The “Clear Models” menu is used to clear one or more of the
INTRAC Model, the IESS-412 Model or the NORAD model. Clearing the INTRAC Model clears the current satellite model. Selecting Auto Continue after this clearing will cause the INTRAC to enter Learning Mode.
Clearing the IESS-412 or NORAD Models simply marks the
ephemeris data as being no longer valid. Selecting IESS-412 or NORAD for Rapid Model Generate or Program Track will cause the menu to jump to the Edit IESS or NORAD data menus for new data to be input. Also clearing the data will mean that Reserve Model will not function.
ANTENNA MOTION LIMITS The INTRAC-305 has user setable software limits to confine
the antenna movement. If a limit is reached in an automatic mode drive is inhibited, the INTRAC emters Standby Mode, a primary alarm is raised and the System Alarm indicator is
Page 62 INTRAC-305 MANUAL - Issue 3.2 © 2011 Advantech Wireless

INTRAC-305 TECHNICAL DESCRIPTION
illuminated. The alarm may be viewed using the Show Alarms menu.
The Soft Limits are set in the Configuration - Soft Limits menu. Note In either Manual (P) or Manual (A) mode the antenna may be
driven through the soft limits with no warning.
AXES POSITION Resolver units are fitted to the driven axes of the antenna.
These units supply positional information to the INTRAC’s
resolver interface circuits.
Depending on the system “Extended Azimuth” or “EG-01”
and/or “Geared Pol” offsets may need to be set.
Fine Tune offsets may be set to calibrate the resolver outputs
to the actual antenna pointing angle.
TRACKING SIGNAL An L-band Integrated Beacon Receiver (IBR-L) is an option
with the INTRAC-305. When fitted this receiver is tuned to an L-band frequency by the INTRAC based on the “Beacon
Frequency” set for the satellite. If the beacon frequency of the
satellite to be tracked is not in the L-band a Block Down Converter will be required to convert the signal to L-band.
The calculation of the correct L-band frequency for the IBR-L is
performed automatically by the INTRAC for BDCs with standard local Oscillator frequencies so that the beacon frequency may be entered at the actual receive frequency.
Note If an IBR-L is not fitted the INTRAC requires a dc voltage level
which is proportional to the received signal strength from the satellite.

INTRAC-305 INSTALLATION
6. INSTALLATION
Introduction The INTRAC-305 Intelligent Tracking Antenna Controller is a
direct physical replacement for the Andrew APC300 Antenna Steptrack Controller. All that is required for the installation is to remove the APC300 and replace it with the INTRAC-305 and then set-up the INTRAC-305 for the antenna system.
This section provides information on connections and set-up. The INTRAC-305 requires that certain parameters be set and
certain information be input before it will be able to function correctly. Some of this information can be obtained from the APC300 but some will need to be obtained from other sources. The chart below gives the parameters required by the INTRAC-305. Four items under “Fitted Options” should
be set to “Not Fitted” (as indicated) as they are not applicable
to APC300 systems. For more information on these settings see section 3-Operation of this manual.

Serial Port Usage The three ports can be used to connect a Remote Control
Terminal, to monitor diagnostic data or to monitor angle data. The specific uses for each port are:-
Remote Port A Remote Control and Monitoring Terminal may be
connected to this port.
Diagnostic data can be monitored by selecting “Diagnostics
On” in the “Function - Configuration” menu. Remote control
of the INTRAC is achieved only if “Diagnostics Off” is selected
in the Configuration menu.
Test Port 1 Diagnostic data is also available at this port together with
Angles data. The selection between Diagnostics and Angles
is made by Menu Key 4 on the “Function - Configuration” menu. The key switches between “Test Port-1 Diags” and “Test Port-1 Angles”
Test Port 2 This port is for a Remote Control Terminal only. The Remote Port allows one PC to be used as a remote
control unit and as a diagnostics monitoring unit. However it cannot do both at the same time.
Note For correct remote control of the INTRAC-305 via the
Remote Port Diagnostics must be set to OFF. Diagnostic data can be monitored during remote operation by using a second PC connected to Test Port 1.

INTRAC-305 INSTALLATION
Beacon Signal Connector When an IBR-L beacon receiver is fitted there will be a
“N-type” RF connector on the INTRAC rear panel. It is to this
that the beacon signal is connected.
Note 18Vdc may be connected to the inner connector of the N-type
in order to power the Block Down Converter.
The 18V can be removed from the “N” connector by power
connector J41 on the INTRAC Interface board.
Signal Strength Input Where no IBR-L is fitted the INTRAC-305 requires a dc
voltage generated by an external receiver. This voltage must be directly proportional to the received signal strength in dB. The signal strength input is via a BNC connector on the INTRAC rear panel.
Resolvers (pointing angles) Setting the INTRAC-305 for the antenna pointing angles is
achieved by use of the “Fine Tune” sense and offsets facility.
Fine Tune Sense is used to set the INTRAC for the rotational
direction of the resolvers. Fine Tune Offset is used to adjust the resolver returned angle to the actual antenna pointing angle. i.e., to compensate for any inaccuracy in the resolver mounting.
Ensure that the “Fine Tune Sense” is set to true (see page
35) for both Az, El & Pol. Also clear the “Fine Tune Offsets”
(see page 36).
With the resolvers connected to the INTRAC-305 note down
the displayed Az, El and Pol antenna pointing angles
Put the INTRAC into Manual Mode. Fine Tune Sense Drive the antenna slowly in Az using the “drive right” key, note
whether the displayed angle increases or decreases. Return the antenna to the original pointing angle. Drive the antenna slowly in El using the “drive up” key, note whether the displayed angle increases or decreases. Drive the antenna
polarisation slowly clockwise using the “drive right” key, note
whether the displayed angle increases or decreases.
For the axes where the displayed angle increased leave the
Fine Tune Sense set to true. For the axes where the displayed angle decreased set the sense to false.
Fine Tune Offsets Use the Fine Tune Offset facility to set the pointing angles to
those noted from the APC300 before it was disconnected.
Southern Hemisphere Set-up in the Southern Hemisphere is the same as for the
Northern Hemisphere except that the antenna rotation will be +/- 90 of North instead of +/- 90 of South.
© 2011 Advantech Wireless INTRAC-305 MANUAL - Issue 3.2 Page 73
INSTALLATION INTRAC-305
Selection of Southern or Northern Hemisphere within the
INTRAC is automatic based on a positive or negative input for Latitude in System Setup - Station Co-ordinates.
TRACKING SIGNAL INPUT The tracking signal may be provided as a dc voltage from an
external receiver or from the optional IBR-L internal receiver.
With IBR-L The IBR-L requires a L-band beacon signal at a level within
the range -80dBm to -45dBm with a carrier to noise ratio (C/No) of better than 40dBHz. To allow some margin for exceptional propagation conditions we suggest that the normal clear sky level when peaked on the satellite should be in the range -70dBm to -50dBm. Severe signal fades will be handled by the INTRAC algorithm entering Prediction mode for the duration of the fade.
If the signal is greater than -50dBm attenuation must be
inserted and if it is lower than -80dBm a higher gain LNA/LNB must be used.
An input level of -45dBm corresponds to a displayed level of
+25dB.
Note In some installations the LNA/LNB power is carried on the L-
band signal cable and special arrangements have to be made to ensure continuity for the dc power when attenuation is added in this cable.
Without IBR-L The tracking signal, provided from an external receiver, needs
to be a dc voltage between -10v and +10v. This voltage should vary proportionally (in dBs) with the received signal strength.
The INTRAC can be adjusted for a fixed offset and a
proportionality constant between 0.1v/dB and 1.0v/dB in either polarity.
Setting offset & gain Connect a switchable attenuator in the IF feed to the tracking
(beacon) receiver.
Connect the dc tracking signal to the INTRAC Signal Strength
Input BNC. Remove the top cover to the INTRAC-305. Link J31 and potentiometers R12 & R55 are used in the set-
up. Link J31 can be changed for -ve or +ve polarity signals. R12 adjusts the gain of the tracking signal buffer. R55 adjusts the offset.
Set the switchable attenuator to 0 dB. Adjust R55 so that the signal level displayed on the
INTRAC-305 is between -10dB and +20dB. Adjust R12 so that 2dB attenuation of the receiver IF signal
causes the displayed signal to decrease by 2.0dB.
Page 74 INTRAC-305 MANUAL - Issue 3.2 ©2011 Advantech Wireless

INTRAC-305 INSTALLATION
Finally adjust R55 to read +20dB when the maximum clear
sky tracking signal is being received.
Note It may be necessary to adjust the links J31 depending on the
polarity of the tracking signal. The link options are both links should be either vertical or horizontal.
OPERATIONAL CHECKS Manual Operation This test checks the operation of the motor drives and limit
switches.
Ensure that all limit and interlock switches are in the normal
operating condition.
Switch on the INTRAC. If the System Alarm indicator
illuminates press the Standby key. If it remains illuminated view the Show Alarms display to what is causing the alarm.
Take the necessary action to clear the cause(s) of the alarm. Select Manual (P) Mode from the New Mode menu. Using the Manual Control keys drive the antenna to the full
extent of its travel in each direction. Confirm that the antenna
actually moves in the required direction. Check that when a
limit switch is reached the motor stops and the System Alarm
indicator illuminates. Note Only one Manual Control key should be pressed at one time
and it should be fully released before pressing another control
key. If a Dual Speed Motor Drive Cabinet is fitted check that the
“FAST” key operates correctly. Pressing the “FAST” key
when pressing a Manual Control key should latch fast drive in
the required direction. Pressing any Manual Key when in
latched Fast Drive should have no effect. Pressing the Fast
key again should remove drive.
Emergency Stop Check Check the operation of the front panel Emergency Stop
switch by pressing it when one or more motor’s is running.
Ensure that the motor(s) stop and will not re-start until the
Emergency Stop switch is released and the and the
appropriate drive command re-instated.

INSTALLATION INTRAC-305
If external emergency stop switches are fitted check their
operation in the same way.
It must not be possible to re-start any motor whilst any
emergency stop switch is in the operated state.
Auto Operation After manually pointing the antenna towards the required
satellite use the Search facility to peak the antenna on the satellite. Check that this function works correctly.
Select Auto New Model and check that INTRAC enters
Learning Mode and makes periodic cross scans interspersed with pointing adjustments.
Check that after 24 hours of Learning the INTRAC enters
Tracking Mode.
Remote Control If a Remote Control and Monitoring Terminal (RCM-4)
package has been supplied check that this works correctly.

7. FAULT FINDING
Introduction Advantech AMT Limited recommend that users return faulty
INTRAC-305 units to Advantech AMT Ltd. for repair.
Advantech AMT Ltd. have a specially equipped repair facility
and are able to repair and return a unit rapidly if required.
However if the problem is of an intermittent nature it may be
beneficial to allow us to soak test the unit for a longer period.
A replacement unit may be available from Advantech AMT
Ltd. during the repair period. Please ask for details of this
service. Repairs carried out by Advantech AMT Ltd. are warranted for
90 days. For those users who would prefer to repair their own unit this
section is intended to help with locating the faults. However :­ Advantech AMT LIMITED ACCEPT NO RESPONSIBILITY
OR LIABILITY FOR ANY HARM CAUSED TO ANY THIRD
PARTY PERSONNEL FROM WORKING INSIDE THE
INTRAC-305. Advantech AMT LIMITED ACCEPT NO RESPONSIBILITY
OR LIABILITY FOR ANY DAMAGE CAUSED TO THE
INTRAC-305 BY ANY THIRD PARTY PERSONNEL AS A
DIRECT OR INDIRECT RESULT OF THIS SECTION OF
THIS MANUAL. ANY THIRD PARTY WORK INSIDE THE INTRAC-305
DURING THE WARRANTY PERIOD WILL INVALIDATE
THE WARRANTY
Because the INTRAC-305 forms part of a system, parts of
which respond to signals from the INTRAC-305 and parts of
which send signals to the INTRAC-305, deciding whether a
fault lies with the INTRAC-305 or the external equipment can
be difficult. The simplest method to prove if the fault lies with the
INTRAC-305 or some other equipment is to replace the
INTRAC with a spare unit. However care must be taken in
such a case that any fault with the external equipment does
© Advantech Wireless INTRAC-305 MANUAL - Issue 3.2 Page 77
not cause damage to the replacement INTRAC. Also you
must ensure that the replacement unit is set correctly for the
installation.
Voltages should be within 5% of stated values
FAULT FINDING INTRAC-305
This fault finding guide goes no further than the replacement
of the major assemblies such as power supply, IBR-L or
complete printed circuit assemblies. The INTRAC-305 consists of six major assemblies :­ Main Interface PCB
Processor PCB Low voltage power supply LCD Display panel Front panel keys assembly Beacon receiver (optional)
Note The LCD display panel has a replaceable backlight which has
a finite life span. This light will need replacing within the
working life of the INTRAC-305. Included in this section are
instructions on replacing the lamp.
FAULT SYMPTOMS
INTRAC doesn’t appear Check that the main power-on switch glows green when
to power up switched on. If not check INTRAC fuse, power cable and
power source Display screen blank/dark Data is visible on screen but display is very dark.
Try to adjust display brightness and contrast. Contrast
adjustment has some effect but brightness has none. LCD backlight or its inverter has failed.
Note To adjust brightness or contrast press menu keys 2 - 4 - 5
followed by the Enter key. Menu key 4 will now control
brightness and menu key 3 will control contrast. Display is bright but there is no data visible. Brightness
control has some effect but contrast does not. Check power supply voltages :-
V1 = +5v to com ) V2 = +15v to com ) V3 = 12v across + & ) V4 = 24v across + & )
If voltages are correct fault is with LCD, ribbon cable to J18
(Interface PCB) or the Interface PCB itself.
Replacing the LCD backlight This section applies only to units fitted with a display with a
fluorescent tube backlight (blue display). Some units may be
fitted with a LED backlight display (grey display) which do not
require replacement of the backlight. Remove the top cover from the INTRAC-305. The rear of the
LCD panel is then visible.

RETAINING PIN
INTRAC-305 FAULT FINDING
Disconnect the two lamp wires from the orange connector at
the front corner of the Interface PCB. Disconnect the LCD panel flex cable from Connector J64 on the Interface PCB.
Remove the four screws which hold the INTRAC front panel
to the sides and drop down the front panel. Remove the four nuts which hold the display assembly to the front panel and remove the display unit from the front panel. Lay it face down on a soft surface.
Press down on the centre of the two retainers (see diagrams)
Turn the display face up. Remove the retainer pins. Remove
the metal cover.
Turn the display face down on a soft surface. Gently slide the
backlight unit from the display unit. (see diagram)
Remove the three tapes which secure the lamp reflector. Remove the lamp and wire assembly.
© Advantech Wireless INTRAC-305 MANUAL - Issue 3.2 Page 79
FAULT FINDING INTRAC-305
Install new lamp and wire assembly. Wrap reflector sheet around lamp. Replace securing tapes to secure reflector. Turn unit face up and ensure that backlight is free from
contamination - dust may be blown free. Slide backlight into display unit. Replace metal cover over backlight. Replace retainers, press centre to secure. Locate display unit over the four studs and fit the nuts. Re-fit INTRAC front panel to side panels, reconnect flex cable
and lamp wires. Replace INTRAC top cover, reconnect power, switch on and
verify that the lamp illuminates.
Some, or all, front panel The six menu keys, the numerical keypad and the manual keys do not function control keys are all connected in a matrix. There are three
supply lines to the matrix and eight return lines. If any one of
these lines fails at least three keys will cease to function. The
fault may be the ribbon cable to J27 (Interface PCB), the
connectors or the Interface PCB itself. If only one key does not function the fault will be with that key
and the front panel PCB will have to be replaced. This board
is held on the front panel by six threaded studs. Disconnect
the ribbon cable and the emergency stop switch (note which
wire goes to which terminal). Remove the six nuts and lift the
PCB off the studs.
Emergency Stop Switch Fails Pressing the front panel emergency stop switch should cause
the System Alarm indicator to illuminate and the INTRAC to
enter Standby Mode. The switch consists of two normally closed (N.C.) contacts
pressing the switch opens both sets of contacts. The switch
connects to the Interface PCB through the front panel PCB
and the ribbon cable. If the switches are OK and there is
continuity to connector J27 on the Interface board the fault is
on that board.
Pointing Angles Incorrect The resolvers consist of three coils two of which move with
respect to the third. A continuous signal is sent from the
INTRAC to the fixed coil and is induced into the other two
coils. The amount of induction in each coil is dependant on
the respective position of the coils. The signal sent from the INTRAC is the same for all
resolvers. angles constantly varying Constantly changing angles is caused by noise on the two
return signal lines. This implies that the source signal is not
present in the resolver. For one angle (i.e. Az, El or Pol) to
be changing either the circuit to the resolver is broken or the
resolver itself is faulty.

INTRAC-305 FAULT FINDING
If all the angles are changing the fault is on the Interface
PCB.
wrong angle displayed If the displayed angle changes to be near 0 or 90 it is
probable that one of the two return signal circuits from the resolver is broken or the resolver itself is faulty.
If the displayed angle changes to any angle other than near
0 or 90 the fault is on the Interface PCB.
angle doesn’t change If the displayed angle doesn’t change when the antenna is when antenna is moved being driven first ensure that the antenna is actually moving in
the relevant plane. Select Manual Mode and drive the antenna in the appropriate direction and either check that the beacon level changes or actually look at the antenna.
If the antenna moves but the displayed angle does not
change the problem is the connection of the resolver to the antenna.
No Antenna Drive Check that the LEDs in the Manual Control keys illuminate
when antenna drive is commanded. If not the fault is on the Interface PCB.
The Motor Controls connector (50-way D-type) on INTRAC
rear panel outputs +12v and ground to for each drive signal. The +12v and ground levels are switched to the approriate pins of the connector by relays. One relay switches +12v for all Az drive commands, another does so for all El drive commands and a third for Pol drive. The ground level is switched by changeover relays, one does Az West or East, another Az Fast or Slow, another El Down or Up, another El Fast or Slow and another for Pol CCW or CW.
The table below indicates across which two pins of the 50
way connector there should be 12v for each drive condition.
example Elevation Up Fast - there should be 12v across pins 23 & 6
(El Up) and across 24 & 7 (El Fast).
If the drive signals from the INTRAC are correct the fault lies
with the Motor Drive Cabinet, the antenna drive motors or the intervening wiring.
© Advantech Wireless INTRAC-305 MANUAL - Issue 3.2 Page 81
FAULT FINDING INTRAC-305
Tracking Signal (IBR-L) If the beacon signal falls to a non-usable level the INTRAC
automatically enters Predicting Mode and continues to track
the satellite from the model. There is no way of knowing from
the INTRAC whether the loss of signal is due to the satellite
or the IBR-L. Thus when the displayed beacon level falls
below normal the user should check the signal by some other
means before assuming an IBR-L problem. The beacon
should be checked with a spectrum analyser on a narrow
sweep range so that the actual beacon frequency can be
seen and measured. Although the loss of or reduction in displayed beacon level
could be caused by a fault on the Interface PCB the most
likely cause is a faulty IBR-L.
