A Low Cost Attitude and Heading Reference System

Real-time control should be conducted to the moving attitude during the autonomous flight of small unmanned aerial vehicle. The movement information of small unmanned aerial vehicle needed for control system is obtained through inertial measuring sensor. The information fusion algorithm can be designed through the original data obtained by this sensor so that the necessary state information can be provided for flight control system. In this paper, the design and implementation of a low cost Attitude and Heading Reference System is discussed, and the algorithm has been applied to the attitude control of small unmanned helicopter.
