thinking of how to get airborne drone RDF working when I came upon
this site.<br>

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 think that is pretty cool.<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>
