Design of Online Calibration andError Compensation of Differential GPS/SINS Ultra-Tight I ntegration
摘要
Abstract
In order to further improve the navigation accuracy and error calibration accuracy of the GPS/SINS ultra-tight integrated system , a scheme for GPS/SINS ultra-tight integrated navigation system based on carrier phase difference is proposed .On the one hand ,by aiding GPS tracking loop with the SINS, the carrier loop noise bandwidth and the code correlator spacing are reduced , the tracking precision of carrier ring and code loop are improved.On the other hand , the high precision measurement informa-tion is provided as integrated navigation measurement by carrier phase , which can accurately calibrate and compensate the IMU error .The navigation accuracy of GPS S/INS ultra-tight integrated system is improved further .关键词
