We have experienced fly aways on a couple different occasions.
The first time we believed it was because of a power issue causing our on board computer to die.
However, this time we remained connected to our on board computer as the drone flew away. Here is the flight log.
I noticed on both flights we experienced the Gps fusion timeout. This makes sense as it acted as if it was trying to get to a different location that it was never at. I found some forums online and someone recommended this script PX4-Autopilot/process_logdata_ekf.py at main · PX4/PX4-Autopilot · GitHub
I ran my log through that and got these results log_9_2018-12-12-16-40-46.pdf (178.6 KB)
The vibration gets so bad that it is unflying, but I’m not sure if this happens right before or after we lose gps fusion sensors. Can anyone help with this or guide me in the right direction to fix this problem? It is very troubling that we cannot reproduce this and it only happens about once in every 50 flights.
