Description
External
Heading input from the vesselʼs gyro compass (default).
If there is no heading input due to failure, alarms are raised and the
antenna continues in gyro-free mode. When heading input is available
again and a new acquisition is made, alarms are cleared.
Fixed
Use this setting for an azimuth and cable calibration if there is no input
from the vesselʼs gyro compass and for permanent installations like
remote areas or oil rigs, or during training and test.
For
Fixed
, enter the vessel heading in degrees. If the heading is not
