Normally mission planner will let me know when my compass offsets are high and will deny arming/takeoff. Today, I was able to to takeoff and get a good flight in, but during decent, my craft tilted to one side and crashed somewhat gracefully. After reviewing the logs, I noticed that the X and Y values of my compass were almost touching! Well over 50 flights on this craft, with no problems before this. No GPS glitches or errors in the logs. The auto-analysis, however says the compasses failed.
Is there a way for me to catch bad compass offsets in preflight? The log is too large for me to upload so here is a picture of the compasses.
Any insight would be appreciated!
