摘要
电离层延迟是影响全球卫星导航系统精密定位的主要误差源之一。本文介绍了常用的NeQuick模型和IRI模型,利用两模型进行了中国地区电离层TEC相关计算,将计算值与电离层参考值进行比较,得出了关于区域电离层TEC的有益结论。
Ionospheric delay is the main error source to influence the accuracy of the global navigation satellite system precise positioning. This paper introduces the NeQuick model and IRI model in common use and do some calculate about ionospheric TEC respectively with them. Comparing with the reference value, the results of the comparisons are analyzed. At last we sum up conclusions about regional ionospheric activities.
