北斗星基增强系统的参考站布站设计与分析
|
摘要
随着北斗三号系统建设,系统服务性能不断提升,星基增强系统可以增强北斗系统的定位精度和完好性服务等性能,满足高精度用户的需求。地面参考站是星基增强系统的重要组成部分,它们的布局、数据采集与地面传输网络等对星基增强系统的服务性能具有重要的影响。从中国地壳监测网中选取25个参考站作为北斗星基增强系统的布站方案,对中国区域参考站的几何定轨条件,卫星可视性以及电离层穿刺点分布和数量等指标进行分析,研究北斗星基增强系统地面参考站布局原则,有利于星基增强系统的地面数据传输网络的建设,并给出中国区域地面参考站的布局建议。
With the construction of BDS, the system service performance is continuously improved. SBAS can enhance the positioning accuracy and integrity service of the Beidou system and meet the needs of highprecision users. The ground reference stations are important part of SBAS, and their layout, data acquisition and ground transmission network have important impacts on the service performance of SBAS. 25 reference stations are selected from the Chinese crust monitoring network as the layout scheme of Beidou SBAS. The geometric orbit determination conditions, satellite visibility and distribution and quantity of ionospheric puncture points are analyzed. The research on the layout principle of the ground reference station of Beidou SBAS would be beneficial to the construction of ground data transmission network of the system, and some suggestions on the layout of ground reference stations in China are given.
