摘要
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。结果表明:GPS-Galileo组合定位系统在上述仿真情况下的定位性能良好,GPS-Galileo组合定位系统在实际定位中是可行的。
The differences of the GPS and Galileo system are investigated and the solutions for the differences are given. By using an user track, the positioning performance of the GPS, Galileo and the combined one is studied, and also the positioning performance such as the number of the visible satellite and the PDOP value in the region of China and the Nanjing University of Aeronautics and Astronautics（NUAA） standard point is studied. The results show that the positioning performance of the combined system is perfect and the GPS-Galieo combined system is practicable.
