Compass interference causing position instability — May be site-specific magnetic interference.

compass offsets 1871.0. field strength 133.0-2304.0 (normal 185-650). ekf estimation issues: attitude estimators 21.5° apart; altitude 7.1m baro/gps gap; velocity innovation 10.40; position innovation 15.57.

Recommended Action

Recalibrate compass outdoors away from metal. If this recurs at the same location, the site has magnetic interference (buildings, underground cables).

Recommended Action

Let FC warm up before flight. Reduce logging rate if loop time high. Check IMU mounting.
