Tracking 2.4 on its own is worthless since lots of devices use it. You need to decode the messages. I don't know the OTA format of the various common protocols, but I wouldn't be surprised if e.g. Spektrum Air is distinguishable from Spektrum Surface.

However, locating a transmitter which doesn't emit location info would be a problem. Radio location is much more expensive than just receiving signals. Aeroscope appears to be a single unit, and is thus incapable of doing so; you need at least two for triangulation and three for ranging.

No it isn't. See the previously posted pointer provided to an article in this thread in which they (Aerial Armor) describe what they deployed at subject event.

Aerial Armor found drones location (not pilot ) from the GPS data sent in downlink stream, not using triangulation methods.

Multirotors are models too!

I would not be surprised if future (maybe current) DJI controllers have GPS data of the location of he control unit. AND a simple firmware 'upgrade' which DJI is famous for, could add "Home location" to the data stream. Home would be the takeoff position of the drone, where you will likely find the pilot of the drone.

One more reason to not use DJI...

Someone could takeoff then leave the place, move to other location, while drone is in follow me mode
Btw, how is RTH logic performing in this case, return to initial takeoff point, or to actual/last known pilot position ?

I think it varies by model, some can 'follow' and RTH back to initial 'home' or RTH back to you.....

I know that someone has an official permit to fly a drone.
