4. Set SEARCH 1 and 3 AZ (Azimuth) range and EL (Elevation) range. SEARCH 2 is reserved
for future use.
A search pattern 1 or 3 will be initiated according to which GYRO TYPE is selected
and the existence of the gyro input.
Search 1: a search pattern 1 will automatically be initiated when the ship’s heading
input does not exist / is failed. The antenna will go to the relative azimuth position
0º at the calculated elevation and search in the azimuth CCW direction and search
up +0.5º & down -0.5º with a total 6º(±3º) in elevation. The search cycle will repeat
until the antenna receives the lock signal from the modem or the DVB transponder
of the target satellite is decoded by the antenna. If the desired signal is found and
above the predefined detect level, the ACU will enter to Search 3. However, the
antenna will not initiate Search 3 pattern but go into TRACKING mode immediately
if the desired signal is above the predefined tracking threshold level. If the detected
signal is below the predefined tracking threshold level, the search 1 will repeat and
start 3º away from the current position.
