浅析电离层对基于南宁CORS站的网络RTK定位精度的影响

摘要

在低纬度地区，电离层活动较为活跃，对基于CORS站的网络RTK定位精度影响较大，为加强南宁CORS站的应用和服务，本文通过电离层电子密度处理分析软件分析了南宁地区的电离层活动水平情况，并分析了电离层延迟情况及与RTK定位精度之间的关系，得出了一些对基于南宁CORS站的网络RTK定位测量有指导意义的结论。%At lower latitudes,the ionosphere is more likely active than other latitudes,this leads directly affect the positioning accuracy of CORS. For improve application and service of CORS in Nanning,this paper analyzes the iono-spheric active level in Nanning by election density software,and furthermore understand the relationship between iono-spheric delay case and positioning accuracy of RTK. In the end of this paper,some guiding conclusions for CORS in Nan-ning and positioning accuracy of RTK have been obtained.
