摘要
北斗卫星导航系统是中国自行研制的继美国GPS和俄罗斯GLONASS之后第三个成熟的卫星导航系统。本文就北斗卫星导航系统单点定位(SPP)、精密单点定位(PPP)、基线相对定位等算法开展研究,利用实测数据评估了北斗系统的定位性能,为北斗系统进一步应用于地学研究领域打下了一定的基础。评估结果显示,伪距单点定位精度可达10m以内,精密单点定位和基线相对定位精度可达厘米级。
The Bei Dou Navigation Satellite System( COMPASS) is Chinese self-developed satellite navigation system after the U. S. Global Positioning System( GPS) and the Russian GLONASS. In this paper,we carried out research on algorithms of single point positioning( SPP),precise point positioning( PPP) and baseline solutions of Bei Dou system. And then,we assessed the positioning performance of Bei Dou by using real data. The results show that the positioning accuracy of SPP is within 10 m and the positioning accuracy of PPP and baseline solution is at centimeter level.
