9. Setup – Azimuth Trim (IMA Ver 1.05 or greater)
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.
3. Select the satellite that your airtime services will be
provided on in the Satellite Selection dropdown.
4. Refer to the next chapter to enter blockage zones
as desired.
5. After the desired satellite has been acquired, allow
the antenna to track for about 2 minutes BEFORE
clicking Auto Trim.
6. Refer to Setup – Targeting – and follow the
instruction for AUTO TRIM to optimize the
targeting of the antenna.
