Investigation of ionosphere TEC distribution in China region by GIM model

  • Guo Jiming
  • Lin Hui


In this paper, the TEC in China region is calculated by final GIM model and plotted as contour maps, the TEC value calculated from dual frequency GPS measurements (carrier-phase and pseudorange) is used as the reference truth and the TEC values from GIM models are then compared with the reference truth, and the accuracy and performance of GIM model in China region are analyzed and concluded.
