Over the last couple of months we have been working on a tracking antenna for our Ground Station. The objective of this projects is to have high-gain (and thus small beamwidth) antennas for a more stable link up to the UAV whilst it is in flight.
This particular model has a Pixhawk autopilot system on the mount for position and orientation information. It will read the position packets from the incoming telemetry to work out the appropriate yaw and pitch angles to point at the UAV.
Last weekend was the first real-life test of the tracker, albeit with small low gain antennas. It worked very well. The next step is to fit the high gain antennas onto it.
