It seems he uses a USB dongle attached to a Rasp Pi and
listens to the aircraft's ADS-b signal. The signal provides
location and heading. He then uses some math to point a camera
at the aircraft.<br>

I've been thinking of ways to coordinate a swarm of drones.
Transponders make sense. Using the same channel for other
data other than relative position would save weight, like
feeding two birds with the same feeder to paraphrase and old
saying...<br>
