Sea Tel 2400 Dual Band C/Ku Setup – Azimuth Trim
8-1
EAR Controlled - ECCN EAR99
8. Setup – Azimuth Trim
Beginning in IMA software version 1.05, calibrating the targeting of your antenna is much easier. This is accomplished
improving Sky Search and changing the way that Azimuth Trim works so that the need for Home Flag Offset is eliminated.
Azimuth Trim now corrects the relative position of the antenna in all configurations which have valid/accurate
gyrocompass input.
If the antenna has been purposely mounted with the bow mark of the ADE not in alignment with the bow of the ship, such
as for safe entry into the radome hatch, note and enter the approximate offset into the AZ TRIM parameter before
searching for the satellite for the first time. EXAMPLE: The antenna is being mounted on the port side of the ship where it
is unsafe for the hatch to be oriented directly in line with the stern. The installer rotates the ADE so that the bow mark is
facing directly to the port and bolts that ADE into place. When first powering the system up, he will enter +90 in the AZ
TRIM parameter to indicate that the ADE was rotated CW 90 degrees during the installation. This will make
initial satellite
acquisition faster (even though sky search would still find the satellite). This entry is only needed on a new installation that
AUTO TRIM has not been run on yet. If the ADE had been similarly installed on the starboard side -90 degrees would have
been entered to indicate that the ADE was rotated CCW 90 degrees during the installation.
1. Access the Satellite Configuration screen.
2. Select Sky Search as your desired type of search
pattern to use for this initial satellite acquisition on
a newly installed antenna system.
