Background information on 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.
With heading input or fixed heading and Inclined Orbit Satellite
