Conical Scan Tracking
The antenna control unit uses conical scanning to maintain peak
signal strength to the receiver and to update the satellite’s
position. When conical scan tracking is active, the antenna moves
continually with a circular motion to sweep across the satellite’s
peak signal. The signal strength is then fed back to the control
circuits to keep coming back to the direction of the strongest
signal.
If the satellite signal is lost while the system is in conical scan
track mode, the control software imposes a 60-second time-out
delay. If the signal is not regained during that time, the antenna
reverts to the Reacquisition Search to start looking for the satellite
signal.
