Sea Tel 9711-56 IMA Setup – Targeting
12-1
EAR Controlled - ECCN EAR99
12. Setup – Targeting
Optimize the targeting of the antenna to track on or near a desired satellite (/-1 degree.
12.1. AUTO TRIM
The Auto Trim function will automatically calculate and set the required Azimuth and Elevation trim offset
parameters required to properly calibrate the antennas display to the mechanical angle of the antenna itself,
while peaked ON satellite.
After locating the satellite, with Tracking ON,
wait at least 2 minutes before performing the AUTO TRIM,
this will allow sufficient time for the antenna to peak up on the satellite signal and for the targeting loops to
completely stabilize. It is equally important that you verify that the system is tracking the CORRECT satellite
(verify a RX lock indication on the satellite modem).
NOTE: The AUTO TRIM feature is NOT allowed unless all of these conditions are met:
• The antenna must be actively tracking a satellite (AGC above threshold) AND
•
The antenna must have positive SAT ID (RX lock input from the Satellite Modem) AND
•
The elevation angle of the antenna must be LESS than 83 degrees AND
•
The antenna must NOT be set for Inclined Orbit Search AND
•
The system must NOT be set for “No Gyro” mode.
1. To activate the Auto Trim function go to
the Reflector Configuration screen.
