Abstract: A method and system for autonomous or semi-autonomous flight of a flight platform with flight actuators is disclosed. The system comprises a stabilization subsystem for controlling the flight actuators to maintain stabilization of the flight platform in flight and a flight control subsystem for controlling the flight actuators to implement flight control of the flight platform in flight. The two subsystems operate separately, wherein the flight control subsystem is overridden by the stabilization subsystem in an event where the flight platform exceeds a predetermined stabilization threshold until the flight platform regains stability.

Abstract: Differential Global Positioning System receivers (60) are located at the corners of a confined zone and receive signals from Global Positioning System satellites (62). The Differential Global Positioning System receivers (60) aid an aircraft (16) to fly and flight path or combing patten (20) over the confined zone. A vehicle (12) with a trailer (14) may be used to transport the aircraft (16) for use over the confined zone.
