摘要
介绍了利用卫星双向双频(C波段)观测来测定电离层时延的方法,并对不同经纬度的观测结果进行了比较和分析。卫星双向双频(C波段)观测精度高,采样间隔短,能测定电离层总电子含量的细微变化。
A method of determing the ionospheric delay with the two-way satellite dual-frequency（C band） observation is introduced, and the results from the observations for different longitudes and latitudes are analysed and compared to each other. The two-way satellite dual-frequency（C band）observation is characterized by high accuracy and fast sampling and can detect the slight change in the total electron content of the ionosphere.
