NOT all kits include the GPS module. Notably the NXP-CUP car kit will not. Instead use the PX4ARMINGBOARD BOARD and stick it down in a convenient location.
The arming board will provide the same beeper and arming buttons. It doesn not (currently) include a compass component.
If provided in your kit, please install the GPS and GPS post mounting, The the pieces needed are listed in the WITB GPS Module page.
Important notes: 1) Install the base plate with the clamping screw pointing either forward-right or forward-left. This will allow you to loosen/tighten even when the plastic rear piece is installed.
2) install the GPS so that the arrow is pointing forward on the B3RB
3) Zip tie the cable so that it stays tight against the carbon fiber mounting tube. This is to minimize interference with the LIDAR beam
4) Don't tighten down the mast clamping scews, you will need to remove the GPS top or the GPS and the MAST in future steps. Tighten them only enough so the parts can still wiggle and be removed.
There is a set of screws that comes with the GPS unit. Use the 4 longer screws and Nylock Lock Nuts to attach the base mount.
It should be placed in this furthest back position:
Attach the mounting mast rod and fasten it with one of the smaller two screws left. Only loosly tighten these screws. Attach the top mount with the remaining screw. Keep it only loosely tighened as well. It should look like this when completed:
Locate the M10 GPS and the 3M double tape.
Attach the double tape in the center of the top mount.
Carefully align the GPS in the center of this tape. Ensure the arrow on the GPS module is facing forward. The cable of the GPS should be zip tied so it stays very close to the GPS mast in order to not obstruct the LIDAR sensor.
