I’m doubting the police radio did this.
None of this is probably very helpful but - its more of a chunk of thought out of my head. I’ve helped my brother troubleshoot some compass issues like this…flying in a location that is similar to this.
Compass readings are hardly a static thing and based on my personal observations (meaning I’m no authority on the subject by any means), are worse when yaw-ing, or moving laterally which kind of makes sense to me.
I’ve seen the readings go straight into the red, I believe even higher than this (like 40% or more) with no fly away or anything near what’s happening with you in this instance. And it seemed to be a fairly quick anomaly in just about every case.
This happen to us when he had a Gopro 3 wifi turned on, which interfered with the RC. But I attributed that to the radio, which was constantly giving us RSSI low warnings - and turned out to have a problem. A new radio solved that one. I’ve had no issues running 2.4ghz right next to my transmitter, in flight (using a pi companion - even though people say it’s a bad idea). I’ve had my pi setup with 2 wifi dongles - one which connected to the gopro wireless on startup, and sent wget control through the pi for camera control. I didn’t have any specific interference or noticeable loss in signal from it.
I had an issue like this on mine, when one time my gps mount came loose…the gps fell and was hanging upside down by the cable. We somehow managed to land it but what a journey lol.
I don’t see the police vehicle anywhere in the video prior to this happening.
I also don’t know of any system or equipment that police use that would interfere with our drones.
I wonder if that building across the street might have some type of microwave emissions for radio or even a long range style directional wifi or something that you just happened to cross into the direct path of. It looks like it could be some type of public works facility and that wouldn’t be uncommon in a place like that - the wireless and radio stuff that is.
2.4g devices are friggin everywhere and some of them can quickly overwhelm others.
You had just finished a waypoint - it appeared - when this occurred. I’ve been a dodo head before and set my waypoints wrong and had some weirdness like this.
Just some thoughts - that sucks when it’s questionable why something like this happens.
