【摘要】：随着北斗卫星导航系统的发展日益成熟,开发基于北斗的星基增强系统已刻不容缓,而电离层误差是影响星基增强系统定位精度的重要误差源。利用中国大陆构造环境监测网络的10个GNSS参考站在2016年3月20日的观测数据,验证了基于北斗导航系统的星基增强系统格网电离层修正算法在中国地区部分站点的修正精度,与Klobuchar模型修正法进行了对比,并检验了格网电离层垂直延迟的修正误差GIVE。结果表明,格网电离层修正算法的修正精度普遍优于Klobuchar模型修正法;修正误差也在正常范围内,进一步说明格网电离层延迟算法在中国地区的应用是可行的。
[Abstract]:With the development of Beidou satellite navigation system, it is urgent to develop the beidou satellite based augmentation system, and the ionospheric error is an important error source that affects the positioning accuracy of the satellite based augmentation system. Based on the observation data of 10 GNSS reference stations in the mainland of China on March 20, 2016, the accuracy of the ionospheric correction algorithm for space-based augmentation system based on Beidou navigation system is verified in some stations in China. Compared with the Klobuchar model correction method, the correction error GIVE. of grid ionospheric vertical delay is tested. The results show that the correction accuracy of the grid ionospheric correction algorithm is generally superior to that of the Klobuchar model correction method, and the correction error is within the normal range, which further shows that the grid ionospheric delay algorithm is feasible in China.
