Mounting Tips
hex.aero proficnc.com
When mounting the GPS to your vehicle, place the
GPS module (with antenna facing up) outside your
vehicle with a clear view of the sky, as far as
possible from potential sources of magnetic
interference such as motors and speed controllers.
For copters and rovers, we recommend elevating
the GPS module.
