| Abstract: | In this paper,the BDS/GPS/GLONASS three-system RTK mapping algorithm is introduced.The mathematical model of BDS/GPS/GLONASS three-system RTK is introduced,which solves the problem of uniformity of time-space reference for multi-mode fusion navigation and positioning.A method of determining the Kalman filter parameters in real-time dynamic location is proposed.The BDS/GPS/GLONASS RTK localization program is compiled and the 28 m ultrashort baseline and 31 km short baseline data are calculated. The positioning results of BDS,GPS,GLONASS,BDS/GPS,BDS/GLONASS,GPS/GLONASS,BDS/GPS/GLONASS are analyzed and compared. |
