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.
Figure 5-5: Acquisition, search pattern
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.
Without heading input and not fixed heading (Gyro-free)
1. A box search pattern is started and the positions with reception of RF power are
checked for up to 10 seconds. If RX lock is detected for more than 20% of the time, the
antenna goes to Tracking.
