摘要 讨论了建立基于EOF(empirical orthogonal runction)的实时三维电离层模型的方法,利用欧洲区域14个IGS跟踪站全天的观测数据模拟实时数据流进行了实验,将这种方法与二维球谐函数模型的结果进行了比较,结果显示基于EOF的实时三维电离层模型全天的模型残差以及与实测值偏差的均方根都在0.2 m以内,优于二维球谐函数模型。 The method of real time Ionosphere Tomography Based on EOF is detailed in this paper.Data from 14 IGS stations of Europe were collected for experiment.The result of both residual and error shows that the method of Ionosphere Tomography provide more precise ionosphere correction than 2-D spherical harmonic function method.The RMS of EOF based Tomography in the experiment shows to be in magnitude of less than 0.2 m.
