Setup – Ship’s Gyro Compass 5012-91 Installation Manual
6-1
6. Setup – Ship’s Gyro Compass
The Ships Gyro Compass connection provides true heading (heading of the ship relative to true North) input to the system. This
allows the ICU to target the antenna to a “true” Azimuth position to acquire any desired satellite.
After targeting, this input keeps the antenna stabilized in Azimuth (keeps it pointed at the targeted satellite Azimuth).
6.1. Setting the Gyro Type
The GYRO TYPE parameter selects the type of gyro compass interface signal, the appropriate hardware connections,
and the ratio of the expected input signal for ship turning compensation. Default GYRO TYPE parameter for all
systems is Step-By-Step so that the ICU will properly follow for Step-By-Step or NMEA gyro signals.
If the Ships Gyro Compass output is Synchro, or there is NO Gyro Compass, the GYRO TYPE parameter must be set
correctly to properly read and follow the Ships Gyro Compass signal that is being provided. To manually update the
Gyro Type parameter:
1. Go to the Communications Interface screen.
2. Click the Gyro Type drop down menu..
3. Select the correct Gyro type.
