Also further reading it<p>>Traffic management of drones: the Uncrewed Aircraft System Traffic Management or the drone operator can obtain drone location information from its GPS data, however this is vulnerable to jamming or spoofing. They can query the API to verify the drone location, e.g. for law enforcement purposes or to check compliance with approved flight plan.<p>That’s not the real use case since not a single drone (commercial or consumer) is using the builtin GNSS in the modem (if any as most don’t even have modems) as they are usually weak compared to professional ones, the real reason is<p>> or to check compliance with approved flight plan.<p>There! Quick background: consumer drones like DJI are easily trackable by DJI AeroScope [1] which is actively used by police to track these drones in specific events, and now FAA is also requiring the remote ID is an extension to that to cover other drones. However, that doesn’t cover all drones, you have a sub-category of drones that are un-trackable, not easily anyway, the ones that fly over cellular networks, which is a challenge to know since from network perspective it’s just another UE, so what’s the easiest way to know?! Exactly, the builtin gnss, a quick query and you can tell, although I’m still not sure how they will distinguish the normal UE from drone UE. So I wouldn’t be surprised that people are disabling the builtin gnss either by the AT commands or just disconnecting the antennas.<p>[1] <a href="https://www.dji.com/ca/mobile/aeroscope" rel="nofollow noreferrer">https://www.dji.com/ca/mobile/aeroscope</a>
