Connecting to APM 2.6 
This module permits the GPS to be mounted separately from the flight control module so that it can have the best clear (view) of the sky and allows the compass to be distanced from interfering magnetic fields. When mounting the GPS+Compass module: 
- Place the module on the outside of your vehicle (in an elevated position if appropriate) with a clear view of the sky, as far as possible from the motors and ESCs, with the arrow facing forward. 
- Distance the module from DC power wiring and the batteries by at least several inches. 
- Place the module clear of nearby iron containing metallic objects. (Use nylon or non magnetic stainless steel hardware and nylon or aluminum standoffs to mount the module). 
- Twist power and ground wires where possible. 

Setup in Mission Planner 
Note:If the GPS / Magnetometer board is mounted in its correct direction (arrow pointing forward) and the Flight controller board is also mounted right side up with its arrow pointing forward, the (COMPASS_ORIENT) parameter will need to be set to (Roll 180) or"8″ because the compass is upside down under the GPS modules antenna. 
- Start Mission Planner and connect your flight control board: APM or PX4 and select the"Connect"tab. 
- Select the"Hardware"tab, then select the left menu"Mandatory Hardware"tab and then select the"Compass"tab. 
- Select the down arrow in the compass orientation pull down item and select"ROTATION_ROLL_180″.
