DJI PHANTOM 3 COMPASS (PART NO. 11) 

The Replacement Compass for Phantom 3 from DJI provides the aircraft with vital navigation data. Using the heading supplied by the compass the autopilot system is able to determine which way the aircraft is flying. It is also required for certain assisted flying modes, in particular Intelligent Orientation Control (IOC). This compass is specifically for the Phantom 2 Vision, and may not work on other Phantom models or third-party aircraft.
