5.1 Autotracking Multisector AMS Antenna
5.1.1 How Does It Work
The Autotracking with Multisectorial Switchable Antenna AMS
consist of a tracking system (with up to 5 possible panels and one possible
up-down antenna), which has inside a relay controlled by the Receiver.
This solution provides the Receiver with the best signal quality using the
GPS coordinates of the Transmitter and the Receiver. With these GPS
coordinates, the Receiver device sends a control signal to the relay which
is inside the AMS antenna to switch on the most suitable antenna panel in
which the level of the received signal is the highest.
With this control signal, the relay (through a circuit based on PIN diodes)
allows the RF signal of the most suitable panel antenna passing through it.
Then, this signal is sent to the Receiver. It is important to orientate the
AMS antenna correctly, so please make sure that the blue line on the
antenna is faced to the North.
