Phantom also has the Intelligent Orientation Control (IOC) function of the Naza-M autopilot system. Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Intelligent Orientation Control (IOC), wherever the nose points, the forward direction has nothing to do with nose direction: In course lock flying, the forward direction is the same as a recorded nose direction. In home lock flying, the forward direction is the same as the direction from home point to the multi-rotor.
