It allows the user to turn any fixed, rotary wing or multirotor vehicle (even cars and boats) into a fully autonomous vehicle; capable of performing programmed GPS missions with waypoints.
This is designed to be used with the 3DR uBlox GPS with Compass so that the GPS/Compass unit can be mounted further from noise sources than APM itself.
It is capable of performing a wide range of tasks even programmed GPS missions with waypoints (with the optional GPS module). It is a full autopilot capable of autonomous stabilisation, way-point based navigation and two way telemetry with radio telemetry modules.
