| Abstract: | 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. |

| Keywords: | ionospheric delay two-way satellite frequency and time transfer satellite time service |
