Is Position Drift Nomal "on the bench"?


Quadcopter is on the bench.
Pixhawk is powered by USB.
Pixhawk is connected to Mission Planner.
RC Transmitter is OFF.
M8N GPS has a 3D fix with 14 Satellites. HDOP = 0.81

With a map zoom level higher than 16.0 the aircraft icon wanders randomly.

Is this “drift” normal or not?

A brief explanation will be appreciated.


Well, since no one seemed interested I figured it out on my own.

I connected an M8N GPS to uCenter.

The map and deviation plots show the GPS wandering in the same random way the aircraft wanders in Mission Planner.
