Abstract: In this paper, a new data processing method and flow is put forward to calculate the ionospheric VTEC inversely according to the features of the HY-2 satellite radar altimeter data. In order to verify the accuracy and feasibility of the data processing method and flow, the paper compares and analyzes the processed data from the aspects of time, data amount, latitude and longitude. HY-2 VTEC is also compared with the GIM VTEC which is interpolated from the GIM, and it is found that there is a good agreement between the HY-2 VTEC and the GIM VTEC. It shows that the data processing method and flow is suitable and correct. Meanwhile, the differences between HY-2 VTEC and GIM VTEC are larger in the areas where the IGS observation stations are fewer, while the agreement is good and the differences are small in the areas where the IGS observation stations are more.
