Large Vehicle MagCal

When entering the heading info for the Large Vehicle MagCal should I be using the TRUE heading or the MAGNETIC heading?

Thanks.

I would use the magnetic heading and enter the declination (radians) in COMPASS_DEC.

Looks like I may have a bigger problem on my hands. When I tried the calibration I got “Mag 2 failure”. I think I’ll be swapping out this compass and seeing if that makes some of this go away.

Also try switching to EK2/EK3_MAG_CAL to 2 and see how does that work out

Thanks for the idea. Weather and lockdowns are getting in the way of further testing so it could be a while before I get to try this out again. Fingers crossed.
