I am working on a custom rig that runs an A3/LB2/X5R standalone (not on an aircraft).

Technical question about compass calibration: when you do compass calibration, is DJI expecting the IMU (A3 in this case) to be rotated horizontally and vertically simultaneously with the compass/gps antenna or is it just the compass/gps stick that needs to be rotated?   I know they both must be oriented forward but I am trying to figure out if the A3 has to be mounted and rotated together with the compass/antenna during calibration.
