About the acquisition process and search pattern
With heading input or fixed heading
1. The antenna starts the acquisition and searches for 10 seconds at the expected
position. If RX lock is detected the antenna goes to Tracking.
2. If no RX lock is detected, a box search pattern is started and the positions where RF
power can be received are stored.
3. The antenna checks each stored position for up to 10 seconds. If RX lock is detected for
more than 20% of the time, the antenna goes to Tracking.
None I
mportant: You must make an azimuth 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
Note
If you change the heading settings from external to fixed or vice versa you must
make a new azimuth calibration.
Note
If you move outside coverage of the selected system, you will eventually lose
connection to the satellite network. The
