Compass variance

Hey guys,

Running 3.3, and my compass seems all out of whack. I’m getting intermittent “compass variance” and “bad compass health” messages, and while the plane seems to track pretty well along the mission plan, the heading indicated is definitely way out of whack.

I haven’t changed anything on the plane, this just started happening all of the sudden. I’m using the 3DR GPS externally mounted in the same orientation as the PixHawk. I’ve tried multiple compass calibrations to no avail.

Any ideas?
