Hi all, I am trying to get an accurate RTK heading on a flying drone. I read here that the simpleRTK2B+heading requires the two antennas to be at least 1m apart, which is very problematic to do that on a small drone (mavic pro sized). Is there some other way to confiture the RTK2B+heading so I can get an accurate heading?
What accuracy should I expect if the antennas are 20cm apart for example?
Anything below 30cm is not recommended. With 30cm distance, in good sky view and static conditions you can achieve 1deg error, but in general you will be at least more n the range of 3-4deg error. Unfortunately the only alternative we can think of is an IMU with magnetometer compensation.
