Is it possible to tell the pixhawk the offset of your GPS mount location from the controller or CG? I would like to mount the GPS in the tail of my copter far away from the gimbal, ESC's and other sources of interference. However this means with 500mm of longitudinal offset, the copter will translate 1m if I yaw 180 degrees. I know my GPS probably isn't super accurate, but I'd still like to keep things as "pure" as possible. Any input is appreciated.
