For improving its positioning and navigation precision and exerting its performance availably, UAVs must inaugurate new navigation application field. Based on analysing theory and limitation of routine UAV DGPS navigation, this paper puts forward a independent navigation method of UAV based on stand-alone star-chain DGPS position technology. The structure model and technique ensureing measures are discussed. Flight examination results clearly reveal the advantages of this method.
