In about 1 of 5 flights the EKF solution errors and can’t recover. Below are some example logs. What are some suggestions as to why this is happening? Vibration? Data dropouts? Too much logging?
I suspect something bad is happening with your GPS/magnetometer. Maybe bad wiring or maybe a bad GPS/Mag card? when I see drop-outs in the “GPS Noise & Jamming” data usually it is because the autopilot has stopped getting data from the GPS module.
Thanks. I was also thinking bad communications. Do you suspect a bad physical connection or noise? It is kinda weird that only MAG_X dropped out but Y and Z did not. Also the GPS seems to go in and out which could be an intermittent connection. I have 3.3V level signaling across a 20 inch wire. Does that seem OK for noise immunity purposes?
