摘要(Abstract)：

针对GLONASS的双差模糊度失去整周特性以及附加模糊度参数的卡尔曼滤波模型,该文提出了一种基于站间单差模糊度分别求解的方法和一种能够在实时动态定位中获得卡尔曼滤波参数的方法,从而实现了BDS/GLONASS双系统联合实时动态差分(RTK)定位。对在石家庄采集的BDS三频与GLONASS双频短基线数据进行了解算,并对比分析了其他定位模式的结果。实验表明,该方法能够正确固定GLONASS模糊度,其单频和双频的模糊度固定率分别为91.2%、99.6%。GLONASS的定位精度与BDS相当。BDS/GLONASS组合定位精度和稳定性相较于单系统也有所改善,其中BDS三频+GLONASS双频的定位精度最高,总体精度为2.22 cm。频率增加缩短了初始化时间,为实现单历元获得固定解提供了可能性。
