Abstract:To solve the problem of the aircraft location accuracy was not high in the automatic landing of the carrier, preci.sion location algorithm based on the satellite navigation and radar was proposed in this paper. In order to improve the loca.tion accuracy of the satellite, the carrier phase difference technique was employed to track the target. For the abnormal da.ta processing, wild data removal was adopted in the satellite and radar tracking. Then, the sequential fusion algorithm wasused. Finally, the proposed algorithm could improve the positioning accuracy of the aircraft.
