Well, I read through this entire thread and it appears only one other person has had an "encounter" that appeared to be the result of RID. I guess I will make that two of us.
Some months ago I was flying at a large hot air balloon event. There was no TFR and it was held in uncontrolled airspace. The NOTAM was minimal. I flew multiple times over a four-day period. I launched from the other side of a body of water and flew out over the water to get footage. I was always upwind of the field and only flew above the empty body of water, i.e., no boaters, swimmers, etc. beneath me. I was never closer than about 600' horizontally from any balloon. I got some great hyperlapses of ascensions and a bunch of regular stills and video.
One morning I was onsite at 7 am, sent up a drone and saw there was no balloon activity at all at the field. The sunrise ascension had been cancelled it turns out. I was only in the air about three minutes. While I was back in my vehicle packing things away, I heard a drone overhead. I looked up through my windshield and there was what appeared to be a Mavic2Pro sitting directly above me at about 30'. I checked Dronescanner, which I always run just to see if anyone else is in the vicinity (and to make sure my RID is working), and there was nothing other than the residual information about the drone I had just landed. The bogey hovered there for about one minute then flew out of my view. About two minutes later it was back and appeared to start a crude grid search of the area. I never got back out of my vehicle and eventually I left. As I was pulling into traffic on the main road, I again saw the drone. This time it was across the road flying low and slow over a parking lot.
I returned to the event one last time that evening and was airborne for almost two hours with no further sightings, nor did I ever see any other drones on Dronescanner.
I wouldn't call this a confrontation, but clearly I was tracked using RID. There's simply no way someone could have seen my drone from the launch field (I was never closer than 1200'). Also, I had been on the ground for a couple of minutes already when the bogey showed up. If it had been close enough to follow my drone (
Mini3Pro which is super-quiet anyway) I surely would have heard it when outside my vehicle.
It is ironic that someone would use RID to track me with a drone that was not transmitting RID itself.
I have long followed the practice of keeping a low profile when flying, so this was a real surprise for me.
Probably it was just another pilot that saw you on the karen app or saw the drone midflight.
I haven't located anyone with the karen app yet, except me, but I visually located around 5 or 6 drones midflight and searched for the pilots, by just following the drone with the telephoto.
So when your out there five miles away and can see what your drone sees on you screen, rest assured those exact same signals (were talking GPS locations, height, speed, direction and a whole lot more) are going out effectively in a ten mile diameter sphere - from your drone. "Your on the list buddy"
All RID did was require manufacturers to 'tweak' the info that was already being freely broadcast, which; (as evidenced by DJI updating older models), is a simple task because 97% of the data (and more) was always being broadcast by us anyway.
The data link between the controller and the drone is encrypted, is not publicly available, and never will unless someone breaks the encryption. Aeroscope knows the encryption and can listen to all that data (it's basically like a man in the middle attack), it could even receive the video feed, but DJI chose not to make that available on the Aeroscope units.
Aeroscope shares basically the same telemetry as RID (or vice versa), but it also shares your DJI account e-mail. The Aeroscope software also has memory and elaborates a heatmap of your flights, and the data collected can be shared with other Aeroscope devices.
I already knew that when I bought my
Mini 2, and that's why I made a specific email for my DJI account/drone related things (because my usual account is just my name and surname and I knew that would be shared around while flying).
RID is a separate non encrypted transmission, publicly available, it's similar, but not the same.
RID may only work locally now, but unlike Aeroscope, it's not proprietary and RID listeners are dirty cheap, so in the future I assume it will be much more like a FlightRadar24 app, that collects the drone data locally from a net of dedicated RID listeners and shares it online.
I can pick a RID package from my
Mavic 3 as far as 3.5Km with my Samsung Tab A7 laying o a table in my garden, a dedicated antenna on a high place could pick drones from 50Km away as long as there is line of sight, much like the Aeroscope fixed antenna.
I don't necessarily think it will be a problem because most confrontations/unwanted interactions are from people at around 300m of the takeoff point anyway. Mostly because they feel their privacy violated, which is true, if you see/hear an unexpected drone flying nearby it is a quite natural reaction to feel observed, even if the drone is at 200m, passing by and looking to the other side.
That being said, I don't feel comfortable sharing my telemetry and location to the public, so whenever a hack is available to turn off RID I'll just pick it, like I always hack my drones to use FCC instead of CE; until then, I already learned to live with it.
