| 摘 要： | 北斗卫星导航系统的开放运行为其在高精度领域的应用提供了可能,系统精密单点定位性能受到了极大关注。本文首先介绍了北斗区域导航系统的星座和BDS/GPS跟踪网,分析了基于国内布站定轨的北斗卫星精密轨道和钟差精度。在此基础上研究了北斗区域导航系统静态、动态精密单点定位精度,并与GPS定位结果进行比较。实测算例表明:北斗精密单点定位可以实现静态厘米级、动态分米级的定位精度,达到目前GPS精密单点定位水平。

| Abstract: | BeiDou navigation satellite system(BDS)has opened service in most of the Asia‐Pacific region, it offers the possibility to break the technological monopoly of GPS in the field of high‐precision applications,so its performance of precise point positioning (PPP)has been a great concern.Firstly,the constellation of BeiDou regional navigation system and BDS/GPS tracking network is introduced.Secondly, the precise ephemeris and clock offset accuracy of BeiDou satellite based on domestic tracking network is analyzed.Finally,the static and kinematic PPP accuracy is studied,and compared with the GPS.The actual measured numerical example shows that the static and kinematic PPP based on BDS can achieve centimeter‐level and decimeter‐level respectively,reaching the current level of GPS precise point positioning. |
