There is no universally agreed definition of an autopilot, but usually it is understood to mean a system for controlling the flight path of a missile, either by moving aerodynamic surfaces or by thrust vector control. Accelerometers and gyroscopes are used to measure the actual flight path through electronic circuitry. The whole makes a closed loop system. (Not all missiles use autopilots.)

A cartesian missile, if it uses an autopilot at all, would usually use two: one for controlling the 'g' in the pitch plane and another for controlling the 'g' in the yaw plane. AUW
