I had two near crashes due to a very strange behavior of the position estimation.
Both times at Autotakeoff (around 14:28:30 and 14:51:30) GPS1 and GPS2 seem to be accurate, but POS and AHR2 Lat and Long values show very strange behavior!
This resulted in the Plane turning sharply to the left during takeoff rotation. By immidiate switching to manual and handflying, the plane could be saved from hitting an obstacle.
Any idea what could have caused this?
