A search pattern 1 or 3 will be initiated according to which gyrocompass type is
selected and the existence of the gyrocompass 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 predened 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 predened tracking threshold level. If the detected signal
is below the predened tracking threshold level, the search 1 will repeat and start 3º
away from the current position.
