摘　　要：实现了BDS/GPS/GLONASS三系统组合RTK定位算法,介绍了BDS/GPS/GLONASS三系统组合RTK数学模型,解决了多模融合导航定位时空基准统一问题,并针对附加模糊度参数的卡尔曼滤波函数模型,提出了一种确定实时动态定位中卡尔曼滤波参数的方法。编制了BDS/GPS/GLONASS RTK定位程序,并对28 m超短基线及31 km短基线实测数据进行了解算。对比分析了BDS、GPS、GLONASS、BDS/GPS、BDS/GLONASS、GPS/GLONASS、BDS/GPS/GLONASS七种模式下的定位结果。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.
