Hi,
We recently had a crash with our P4P RTK where it appears to have suddenly lost power at the end of a mapping mission using Pilot. It finished its mission, triggered RTH, yawed to face its home point then lost power and dropped directly down landing on its landing gear which both snapped off and destroyed gimbal/camera.
Ive had a look at the logs and it had 10 "GPS mismatch error" during the first few waypoints, and the previous flight has 40 of the same error and at least 1 for the previous 8 flights. I know this can be indicative of nothing critical or potentially a compass / GPS / gyro mismatch. I wouldn't have thought this would cause it to suddenly lose all power like that though.
Compass cal was done approx a week before crash and flight area did not change. No significant metal in take off area but was iron ore rich environment. Battery log looks fine no dips in voltage or cell misbalance and had 28% at time of crash.
Any help diagnosing or how to diagnose the failure much appreciated. I have the txt and dat logs and will attempt to attach them to this thread.
Thanks!
