1 General

The

hopf

Sync Module 8024GPS is a GPS Module for the reception and evaluation of GPS
signals for high-precision signal generation and output of time information. In combination with
other hardware output modules, rack vesions and power supplies the module can be "custom­tailored" set-up and used for various applications. The configuration of the GPS settings and
the signal generation is made via the serial remote interface.

Some of the Sync Modules 8024GPS basic functions:

• Simple configuration using

hmc

software on remote interface

• Remote interface (Serial-Remote) on the front panel (RS232 format)

• Status LEDs on the front panel

• Status optical coupler on the front panel

• High freewheel accuracy through GPS-supported regulation of the internal quartz base

• Completely maintenance-free system

• SyncOFF timer (reception failure bypassing) for operation free of fault messages - even

in difficult reception conditions

• Redundant multiple validation of the synchronization signal for fault-free and leap-
free signal evaluation

• Maintenance-free, buffered back-up clock for more than three days

Accessories supplied:

• Serial programming cable KA6870 (2m, 9-pole socket to 9-pole socket) to connect
to a PC.

As the Module 8024GPS is supplied in system build-ups, the build-up of the unit and the
system-specific connections and signal outputs are documented in the accompanying manual.

Not all signal outputs parameterizable via the

hmc

software are always

available as physical outputs for the different system variants.
The available functions and their appropriate physical outputs are stated in

device-specific manual.

3.6.1.4 Time Zone Selection (Time Zone Offset) panel

The panel is used to configure the time zone offset to UTC time for calculation of local standard
time. The operational sign designates the direction of the time zone location in relation to the
prime meridian ('+' for east and '-' for west).

Selecting a Time Zone

There are two ways to select a time zone: Either one of the predefined time zones may be
selected by moving the mouse over the world map, which implies the limitation that not every
theoretically possible time zone offset may be selected. A list of cities within the time zone that
is marked in the map helps finding the correct time zone for a certain place on earth. Of course,
no warranty of any kind is given for the correctness of these lists and other information, and
local time zones are always due to change. Map and lists are merely for convenience.

A time zone can be specified manually too (up to
minute precision). For this purpose, the button

will open a dialog allowing input of the offset
as values direction, hours and minutes.

The operational sign designates the direction in which the local time differs from UTC time:

'+' corresponds to east of the prime meridian (Greenwich)
'-' corresponds to west of the prime meridian (Greenwich)

As most countries of the world select their time offset in whole hours the input is also in steps
of one hour:

e.g. + 05:00 or - 11:00
However, some countries operate with smaller time steps; thus minute-by-minute entry is also

possible:
e.g. + 05:30 or - 08:45

3.6.2 System – Tab

3.6.2.1 SyncON / SyncOFF

These timers can be used to delay the change of status from QUARTZ to SYNC (SyncON
Timer) and from SYNC to QUARTZ (SyncOFF Timer).

The SyncOFF timer is used to bypass reception failure for operation free of fault messages in
difficult reception conditions.

In the event of a synchronization source reception failure (GPS in this instance), the re­synchronization of the system to quartz status (QUEX) is delayed by the configured value. The
system continues to run in synchronous status (SYOF) on the internally regulated, highly
accurate quartz base during this period.

This setting depends primarily on the desired freewheel accuracy.
Example freewheel accuracy calculation

In order to calculate the maximum value to be set for the SyncOFF timer, the desired minimum
system accuracy is divided by the freewheel accuracy value of the quartz. If, for example, the
freewheel accuracy is 1x10E-6 and the desired minimum system accuracy is 5msec. the
following calculation results:

0.005s / 1x10E-6 = 5000s = 83 minutes 20 seconds

 The max. value to be set for the SyncOFF timer is thus 83 minutes.
The SyncON timer is used for systems operating on a highly accurate, regulated quartz base

to ensure that the system does not synchronize before the quartz base has been accurately
regulated. This timer should be set to 00 as default value on Module 8024GPS.

Value range

SyncON

00 ... 30 min

SyncOFF

0002 ... 1440 min

3.6.2.2 Reset

Hardware reset

This button is used to trigger a hardware reset of the module. This leads to a defined restart
of the module's microcontroller.

This function has no effect on the failsafe stored data.

Factory defaults

After activating the Factory defaults - button and an additional confirmation dialog the
settings of Module 8024GPS are reset to factory default.

After setting the Sync Source to factory default values the GPS receiver
needs up to 13 minutes of satellite reception in order to generate the correct
information on the leap second from the GPS data. Only then the Sync
Source (here Module 8024GPS) can be synchronized.

During this time (however only when the GPS receiver really receives
satellites) the following message is displayed in the tab Module Errors:

GPS Receiver in raw data mode - no synchronisation

As long as the DST changeover times for daylight saving time and the time
zone offset are not initially configured after a factory default of the Sync Source
(here Module 8024GPS) the following message is displayed in the tab Module

Errors:
Missing data for Time Zone Offset

and/or

Reception Mode

In this panel the GPS reception mode is adjusted and displayed. The accuracy of the time
evaluation is defined by the exact position calculation of the installation site. For this calculation
(3D evaluation) it is necessary to receive information from at least four (4) satellites. The signal
runtime to several satellites is determined from the calculated position and the precise second
mark is generated from their mean value.

Stationary Mode (Position Fixed) – Standard operation

In Stationary Mode (Fixed position), the GPS receiver calculates its accuracy based on a fixed
position. If four or more satellites are received in this mode, the exact location is updated
automatically.

In this mode, a synchronization with a changing position is not possible.

Automotive (3D)

The automotive (3D) mode allows the use of Sync Module 8024GPS at mobile locations
(except aircraft).

3.6.4 Output – Tab

drops below this value during operation, the signal output stops unless the TimeOFF Timer
has been set greater than 0. In this case the output is done for the duration of the TimeOFF
Timer despite the minimum synchronization status for the output falls below the set value.

The synchronization status is represented from the bottom of the following table (INVA) up
with increasing quality.

Synchronisation Status

SYNC

Time synchronized + quartz control started/running

SYOF

Time synchronized + SyncOFF running

SYSI

Time synchronized as simulation mode
(with no actual GPS reception)

3.6.4.4.2 Status of the Signal Output

The status of the output is stated via a display element with the following color and text
indications:

GREEN

OUTPUT active

There is a signal output

YELLOW

OUTPUT
+ TimeOFF active

There is a signal output
for the duration of the TimeOFF Timer

RED

OUTPUT blocked

There is no signal output

3.6.4.4.3 Output inverted – Polarity of the output Pulse

All outputs stated in the system manuals of the according devices are related to the DEFAULT
setting: Output not inverted.

If nevertheless the inverting of the output signal has to be configured the "Output inverted"
checkbox has to be enabled.

3.6.4.4.4 Special Configuration

If used, the correct settings are described in the additional system manual of the customer­specific device.

Otherwise for S1-S8 the DEFAULT-setting (all checkboxes disabled) should not be changed
due to compatibility reasons.

daylight saving time changeover shall be suppressed.

When setting standard time (winter time), the time offset to local summer time is minus 1 hour.
Standard time runs continuously (without time leap) throughout the whole year.

When setting UTC, the world time (formerly GMT) is used as the time base. This time base
also runs continuously (without time leap) throughout the whole year.

3.6.5 Errors – Tab

This tab displays the current failure status of the Sync Module 8024GPS:

Overview Software Errors

• General Module error (PCID)
If this error occurs even after a Power down, the device is damaged.

• GPS receiver initialization active
This condition might last for max. 1 minute after particular actions.

• Missing data for Time Zone Offset
Difference time (Time Zone Offset) must be initially configured by the user.
Otherwise no synchronization of the Sync Source (here Module 8024GPS) is possible.

• Missing or incomplete data for daylight saving time (DST)
The switchover times for summer/winter time must be initially configured / disabled by

the user.
Otherwise no synchronization of the Sync Source (here Module 8024GPS) is possible.

• SPIO setting error
If this error occurs even after a voltage reset, the support team of company

hopf

needs to be contacted for further actions.

Nottebohmstr. 41 • D-58511 Lüdenscheid • Tel.: [phone] • Fax: [phone] • Internet: http://www.hopf.com • E-Mail: [email protected]

Overview Hardware Errors

• Adjustment of internal quartz frequency error
Problems with the internal quartz regulation of the Sync Source (here Module

8024GPS) have occurred. So the specified accuracy of the Sync Source cannot be
guaranteed anymore.

• Antenna circuit shorted
The Sync Source (here Module 8024GPS) has detected a short circuit in the antenna

system. The antenna system should be checked.
The error can be suppressed if e.g. an amplifier with its own power supply is used.

• Antenna circuit open
The Sync Source (here Module 8024GPS) has detected an open antenna input. The

antenna system should be checked.

• FRAM error
If this error occurs even after a voltage reset, the support team of company

hopf

needs to be contacted for further actions.

• RTC error
If this error occurs when time is configured or synchronized (synchronization status is

not INVA) and and even after a reset of the Sync Source (here Module 8024GPS) the
internal backup clock may be defective.

• GPS receiver communication error
If this error occurs even after a Power-Reset, the support team of company

hopf

needs to be contacted for further actions.

• GPS receiver in raw data mode – no synchronization
If this condition is indicated, the GPS receiver requires special data from the GPS

signal for which it needs up to 13 minutes signal reception of satellites. Only then the
Sync Source (here Module 8024GPS) can be synchronized.

This happens e.g. after resetting the Sync Source parameters to factory default
values.

maximum of 2 are displayed in the GPS tab. However, the values of these
satellites are 50 or higher.

Possible fault:

* The visibility range of the antenna to the sky is restricted.

Case 3:

Effect: 9 satellites in the range of visibility (In View=09), 6 satellites appear in the

GPS tab. The signal to noise ratios are all less than 30. The module does not
synchronize.

Possible faults:

* The cable is too long
* An incorrect type of cable was used for the length of the antenna equipment
* The BNC sockets are not mounted correctly
* The cable is kinked or broken
* The indirect lightning protector is faulty
* Faulty antenna

Case 4:

Effect: The module was working well previously but there has been no reception for

several days. There are 7 satellites in the range of visibility (In View=7).
However, no satellite is displayed.

Possible faults:

* The cable is damaged.
* There was excess voltage on the antenna equipment and the lightning

protection is damaged.
* The antenna is faulty.
* The GPS receiver on the Sync Module 8024GPS is faulty.
* A constructional change has had an effect on the antenna equipment (e.g.

shading of the antenna due to subsequent building work or the subsequent

laying of cables with high alternating fields in the close vicinity of the antenna

cable)

8 Appendix

8.1 GPS (Global Positioning System)

Satellites circumnavigate the earth about twice per day at an altitude of approximately 20,000
km, on 6 different courses and at different angles.

The GPS system was developed based on 18 satellites with 3 replacement satellites. In order
to prevent short-term gaps in coverage the number was increased during development to 21
satellites with 3 replacement satellites. Above any point on the skyline, therefore, there are
always between 6 and 11 satellites visible. Highly precise atomic clocks are on board every
satellite (accuracy min. 1*10

-12

).

A base frequency of 10.23 MHz is taken from the atomic clocks. The two carrier frequencies
used, L1 and L2, are produced from this base frequency.

• Transmission frequency L1 = 154 * Base frequency = 1575.42 MHz

• Transmission frequency L2 = 120 * Base frequency = 1227.60 MHz

Each satellite sends all important navigation and system data by modulation on these two
carrier frequencies. In the public domain, data transmitted on L1 frequency may be evaluated.
The precise time can be calculated from this data by defining the position via the antenna.

The GPS antenna receives the signals of all satellites that are within sighting range above the
skyline and forwards them to the GPS receiver via a coaxial cable. 4 satellites are required for
continuous time evaluation.

Time calculation

The GPS receiver calculates world time UTC (Universal Coordinated Time) from GPS world
time (GPS-UTC) radiated by the satellite, by subtracting the leap seconds; at present (status:
March 2014) world time is running 16 seconds behind GPS-UTC time. The difference is not
constant and changes with the insertion of leap seconds.

The current standard time for the respective time zone is calculated by the addition of a time
offset to the UTC time. The time offset is the time difference between UTC time and the time
zone in which the clock system is situated, is set in the clock system by the user during
commissioning of the clock.

Any DST changeover that is due in the time zone is carried out via a switching function that is
to be configured in the clock system.

Advantages/Disadvantages GPS:

+

High accuracy

+

High security against interference

+

Worldwide application possible

+

High security against failure (terrestrial transmitters are often switched off when bad
weather conditions prevail at the transmission location)

+

High independent clock accuracy

–

Outdoor antenna required

–

Limited antenna cable lengths
