Hi maico-presente,
Had a look at your log.
At 2m39s your Mavic2 into ATTI mode, distance out 221 meter.
No errors about why it entered ATTI, only this "Satellitenpositionsbestimmung aus. Fliege vorsichtig."
GPS sats down to low number and quality of signal to zero, that ofcourse is reason for ATTI.Sometimes this value is set to zero * due to errors, so drone does not use GPS data ; but than the LatLon is still updated during ATTI
* If that happens than this value goes from 4 or 5 to 0 at once.
In your flight is stepped down from 5,4,3 to 0 in almost 1 second.
At 3m28s GPS mode again, in the log same distance out, but in that period some pitch inputs were given so postion must have changed. (plus ofcourse moving if there was wind)
But still the quality of signal only 2, so no updating.
LatLon 41.014202, 28.962670 did not change while you did the flying....reason imo the low number of sats + signal quality.
After a while the GPS signal oke again, so GPS position should become updated BUT at 4m18s the LatLon position changed to 40.113952, 32.996328 ; distance to HP now 355143 meter!
Because distance to home is that high, craft will land at current postion automatically. "Flugger zu weit vom Startpunkt entfernt. Flugger landet jetzt automatisch"
I think DJI should explain why the position did change suddenly to a complete wrong positon, could be a hardware fail in that drone system.
See chart with GPS lines and Flightmode.
cheers
