The Kalman modal of the three-satellites(TS) system was presented,then the extended Kalman filter algorithm for TS/GPS/Galileo system was studied and the structure of the Kalman filter considering the characteristics of the combined system is given.

给出了北斗改进系统(TS)的Kalman滤波模型,进一步研究了用于TS/GPS/Galileo多星座组合系统的扩展Kalman滤波算法,给出了共用系统Kalman滤波器的结构及工作原理图。

The results show that the positioning performance of the combined system is perfect an.

对GPS与Galileo系统组合过程中需要解决的单个系统间的差异问题进行了讨论,并提出了解决方案,结合一段南京航空航天大学(南航)周围的跑车路线对GPS,Galileo和GPS-Galileo组合系统的定位性能进行了实例仿真和分析,并对各系统在南航基准点和中国范围内的可见星数目和位置精度衰减因子(PDOP)值两方面进行了建模仿真和分析。

As compared with GPS system,the availability of the combined system is improved,and it can still meet the aviation performance requirement at large mask angle.

针对该问题,对GPS/Galileo/BD组合系统在中国境内的可用性进行仿真分析,与GPS单系统相比,组合系统的可用性相对单系统有所提高,且截止角较大时,仍能达到可用性要求。
