北斗系统标准单点定位算法研究
|
摘要
北斗卫星导航系统已建成区域导航星座,可在亚太范围提供无源定位、导航和授时服务。本文系统研究了北斗系统标准单点定位算法,采用实测数据对北斗系统和GPS标准单点定位算法进行了算法验证和数据分析。实验结果表明,北斗系统标准单点定位在X、Y和Z方向上的精度分别为7.1 m、9.2 m和13.2 m,GPS标准单点定位在X、Y和Z方向上的精度分别为6.2 m、5.8 m和11.2 m,北斗系统与GPS标准单点定位的三维定位精度基本一致,证明了北斗系统已经具有独立导航定位能力,可为标准导航定位应用提供服务。
Bei Dou navigation satellite system has built the regional navigation constellation and is used for passive positioning,navigation and timing services in the Asia-Pacific region. The algorithm of BDS standard single point positioning was studied systematically in this paper. We verified the algorithm of BDS and GPS standard single point positioning and analyzed the test data. The experiments results show that the X direction accuracy of BDS standard single point positioning is 7.1 m,the Y direction accuracy is 9.2 m,the Z direction accuracy is 13.2 m,the X direction accuracy of GPS standard single point positioning is 6.2 m,the Y direction accuracy is 5.8 m,the Z direction accuracy is 11.2 m. The accuracy in three-dimension direction of BDS and GPS standard single point positioning is roughly equal. This study proved that the Bei Dou navigation satellite system has had the ability of navigation and positioning. BDS can provide the services for standard navigation and positioning.
