GPS/GLONASS组合定位精度分析
|
摘要
为了进一步提高全球卫星导航系统的定位精度,采用欧洲范围内部分可以同时接收GPS和GLONASS观测数据的IGS跟踪站,及中国范围内部分可以同时接收GPS和GLONASS观测数据的CORS站和中国及中国周边的IGS跟踪站,分析Bernese 5.2软件下单系统和双系统定位结果的差异情况,提出分别采用GPS和GPS/GLONASS组合定位的方法进行比较。实验结果表明:采用GPS/GLONASS组合定位比GPS单系统的内符合精度要好;GPS/GLONASS组合定位比GPS单系统的外符合精度在X、Y方向上要好,在Z方向上精度相当;同时由于单系统比双系统的模糊程度低,所以单系统比双系统的计算效率更高。
In order to further improve the positioning accuracy of global navigation satellite system,the paper used some IGS tracking stations of European range which can receive GPS and GLONASS observation data simultaneously,some CORS stations of China range which can receive GPS and GLONASS observation data simultaneously,and some IGS tracking stations of China and surrounding China,to analyze the difference of positioning between the single system and the double system under Bernese5.2software,and proposed the comparative study on GPS and GPS/GLONASS combined positioning.Experimental result showed that the internal accuracy of GPS/GLONASS would be better than that of GPS,the external accuracy of GPS/GLONASS would be better than that of GPS in Xand Ydirections,and be similar with that of GPS in Zdirection.Meanwhile,due to the lower ambiguity degree,the single system would have higher calculation efficiency than the double system.
