Test: Compass = FAIL - Large change in mag_field (83.06%)

Can you help with my new build?

How can I find out if it’s the compass on the pixhawk or the compass in the GPS that is seeing interference?
I’d like to know since I’m building a new plane and need to know what to shield.

More generally, is it ok if I have a battery pack on top of my pixhawk (but not touching it), like in the pictures in this page?
