Customer Support will best be able to help you if you provide them with information about your system.
To gather this information, run the TeraScan script tscaninfo to query the system for the following
information: TeraScan base packages (and version numbers) installed, and platform information such as
operating system, hostname and hostid, bus type, and time since the system was last rebooted.
You should also be prepared to provide Customer Support with any error message associated with the
problem you are experiencing and all standard output and any standard error associated with the technique
you are using.
For a problem concerning data acquisition, include verbatim output of the corresponding
$PASSDIR/schedlog.html file, $PASSDIR/logfiles/pgs/* files, $PASSDIR/logfiles/mtrack/* files and
$PASSDIR/logfiles/*antenna* files.
For additional information, run tscaninfo full to display the same information as tscaninfo plus a list of all
TeraScan packages installed, TeraScan licensing information, last update date for orbital elements (lastoes),
a list of passes on the pass disk (lspass), the acquisition schedule (listsched), TeraScan environment variable
settings, user environment (path, LD_LIBRARY_PATH), user information, disk information
(df -k), and network information.
The best thing to do is to redirect all output to a file and attach the file to an e-mail message.

number.
1.5 TECHNICAL DESCRIPTION
The 1.5m three-axis tracking antenna provides real-time data acquisition from satellites in a polar orbit. The
antenna subsystem consists of the following components (as shown in drawing 70909001 on page 3).
1.5.1 Outdoor Equipment
(see drawing 70909004 on page 27)
a. 1.5m dish mounted on a positioner. This is the tracking antenna.
Two models of antenna are included in this manual:
Model 6003AL: Three servo amplifiers are integrated in the PCU enclosure.
Model 6003L: Three servo amplifiers are mounted on the antenna separate from the PCU.
b. The antenna is mounted inside a protective fiberglass radome. There are two types of radomes:
1) The radome is mounted on a base frame.
2) The radome mounts to the top of a round plate on a pedestal.
c. Mounted at the focal point of the dish is an RHCP feed receiving L-Band or L & S-Bands, one or two
low-noise amplifiers (LNAs), and one or two downconverters.
d. The positioner is controlled by a Pedestal Control Unit (PCU).
e. Power is supplied to the antenna via the antenna control cable from the computer.
f. A coaxial cable connects the antenna to the inside equipment. The IF signal is sent through the
antenna cable to the receiver. Commands from the computer are sent through the antenna cable to
the antenna PCU.
1.5.2 Indoor Equipment
a. For systems with an HR300 or TR100/TR101 receiver, the IF signal from the antenna is split off from
the antenna control cable.
b. The antenna tracking commands are sent to the PCU from the computer.

4.2.1 Antenna Settings
There are no settings or switches to adjust. The antenna is supplied 100-120 VAC – single phase or 220-240 VAC
via the cable from the computer.
4.3 POWER-UP SEQUENCE
4.3.1 Turning on Power to the Antenna
Turn on power to the computer system. This will supply power to the antenna. Note: Do not plug and unplug
the cable at the antenna.
4.3.2 Antenna Motion on Startup
When power is turned on to the antenna, the antenna will go through the following series of motions:
1. The level cage will rotate to 90° elevation (fully counterclockwise) and then return to 0° elevation.
2. The dish will rotate to 45° above level (45° elevation).
3. The cross-level beam will rotate to 90° elevation (level position).
4. 6003L: The positioner azimuth drive will not rotate. Its position is read from the azimuth pot.
6003AL: The azimuth will rotate clockwise until it hits the upper stop. This calibrates the azimuth encoder.
5. Commands to the antenna will not be valid for the first three minutes after power-up (initializing).
4.4 POWER-DOWN SEQUENCE
4.4.1 Turning Off Power to the Antenna
Turn off power to the antenna at the inside equipment.

Section 5: Antenna Operation and
Periodic Maintenance
5.1 ANTENNA TESTING
Notice: Do not run any of the tests described here while the antenna is tracking a satellite pass. The testing
will interfere with any ongoing tracking and data reception. If antenna tracking is in progress, wait until it is
completed before testing the antenna.
The antenna operates unattended under computer control. To verify that the antenna is responding properly
to computer control, enter the following commands. If an error occurs, see Section 7 "Fault Isolation."
1. Test the antenna status by entering:
% ac 1 st <Return>
Note: The status reply should always include the line "Fast Mode". If not, it should be set using
the ^0070 command. See Section 10.2.2.
Sea-going antennas (see section 4.5 on page 81) must have the "Sat Ref Mode" as well, which is set by the
^0071 command.
2. Display the antenna’s current position by entering:
% ac 1 pos <Return>
3. Move the antenna azimuth to 120 degrees by entering:
% ac 1 az 120 <Return>
4. Check the position by re-entering:
% ac 1 pos <Return>
until the azimuth position is shown as 120 degrees.
5. Move the antenna azimuth to 290 degrees by entering:
% ac 1 az 290 <Return>
6. Check the position by re-entering:
% ac 1 pos <Return>
until the azimuth position is shown as 290 degrees.
7. Move the dish elevation to 14.5 degrees by entering:
% ac 1 el 14.5 <Return>
