Heading
mode
Description
External Heading input from the vessel’s 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. See also
Operation in gyro-free
mode on page 5-11.
Fixed Use this setting for making an azimuth and cable calibration if there is no
input from the vessel’s gyro compass and for permanent installations like
remote areas or oil rigs, or during training and test.
Important: Do not use fixed heading mode for vessels underway.
If using fixed heading mode, set to External before leaving port.
None Important: You must make an azimuth and cable calibration with Fixed
before you can use this setting. This is required in order to be able to use
blocking zones. After a successful azimuth and cable calibration you
must change the heading input setting from Fixed to None.
Select this setting after a successful azimuth calibration with Fixed heading if
the system does not have input from the vessel’s gyro compass. See also
