Then you haven't read much about it.Well, I have not seen a reasonable explanation yet. None of the other dji drones use that system and they all work well. Sometimes the simple answer is the right answer. I hope their nuclear missles use that satellite system. The world will be safer.
The M3 uses the US GPS system as well as the European Galileo System and the Chinese Beidou system.
All other DJI drones use GPS and some use Galileo too.
The Beidou system is probably slightly superior to older satellite systems.
But even if there was a problem with it, the M3 still gets signals from two other satellite constellations.
The problem that's affecting the M3 is not a result of using Beidou.
