| Abstract: | Ionospheric error is one of the main errors impacting precision of Global Navigation Satellite System (GNSS) in the GNSS-based precise navigation and orientation. In this paper, disadvantages of current ionospheric models were introduced. Different ionospheric tomography models were expatiated in detail. At the same time, existent issues of present ionospheric tomography were analyzed. In the end, development direction about tomography models was introduced especially. |
