摘　　要：北斗卫星导航系统(BDS)是我国重要空间战略基础设施。为探究北斗精密单点定位(BDS PPP)技术在云南地区民航通信导航中的应用前景,本文基于云南4个地基北斗站动态和静态结果进行评估。静态结果显示,北斗静态定位在北向、东向和天向误差平均为2.1 mm、2.2 mm和5.7 mm,相当于6.5 mm三维定位误差;动态结果显示,北斗动态定位在北向、东向和天向误差平均为0.8 cm、1.0 cm和2.4 cm,相当于2.7 cm三维定位误差。此外,利用北斗系统进行静态和动态定位精度均略优于GPS,可能与北斗系统在我国可见卫星数更充足有关。本文实验结果在一定程度上证明了高精度的BDS PPP技术在云南地区民航通信导航中的应用前景。The BeiDou Navigation Satellite System(BDS)is an important space strategic infrastructure in China.In order to explore the application of BDS-based Precision Point Positioning(BDS PPP)technology in civil aviation communication navigation in Yunnan region,this paper evaluates the static and dynamic accuracies of four ground-based BDS stations in Yunnan Province.The static results show that the average errors of root-mean-square(RMS)for BDS static positioning in the North(N),East(E)and Up(U)directions are 2.1 mm,2.2 mm and 5.7 mm,which is equivalent to 6.5 mm three-dimensional(3D)positioning errors.The dynamic results show that the average errors of RMS for BDS dynamic positioning in the N,E and U directions are 0.8 cm,1.0 cm and 2.4 cm,which is equivalent to 2.7 cm 3D positioning errors.In addition,the static and dynamic positioning accuracy of the BDS is slightly better than that of GPS(Global Position System),which may be due to the more abundant visible satellites of BDS in China.The experimental results of this article to some extent prove the application prospects of high-precision BDS PPP technology in civil aviation communication navigation in Yunnan region.
