Hi, I managed to get an mRobotics Nano Talon up in the air for a few flights. The first flight seemed to be fine; however, on takeoff for the second flight the plane flew on a course nearly 120 degrees off expected to its first waypoint and continued until I initiated RTL, which worked without issues. Pre-arming checks were all good, and everything seemed to be fine prior to launch. An auto analysis of the log from the second flight showed that there was a large change in magnetic field:
Test: Compass = FAIL - Large change in mag_field (141.68%) Max mag field length (927.93) recommended (550.00)
Map of the second flight is below with incorrect course indicated with red arrow. Plane should have been flying between two green waypoints on takeoff.
The auto analysis form the first flight showed the same issue, but not nearly as significant of a change.
Test: Compass = FAIL - Large change in mag_field (35.35%)
Link to logs for both flights: https://dri0-my.sharepoint.com/:f:/g/personal/jd_lancaster_dri_edu/Es77yUpkePNAkyVdfOtKuLIBtHZDhNTO4DMKE4jGyNmjGg?e=oh90MI
Does anyone here have any advice on what may be causing this issue? Admittedly I am not experienced in log analysis. If someone has some time to take a look at the logs, I’d greatly appreciate it.
I should mention that we had large solar arrays north and south of us 1-2 km distance.
Best Regards,
JD
