  • Based on the Ionospheric Pierce Point (IPP) data observed by the Beidou Navigation Satellite System (BDS) as well as Global Positioning System (GPS) and the historical data, a high accuracy modeling method for the Total Electron Content (TEC) of regional two dimensional ionosphere is proposed. The historical data are derived from International Reference Ionosphere (IRI) empirical model. The method can solve the low accuracy problem of short-period ionosphere modeling in the area lacking IPPs and the diverse distribution of IPPs in each period. Virtual IPP data estimated from the IRI model is uniformly inserted in the modeling area, and the dynamic weight value is assigned to the data using the constructed weight calculating formula according to the distance from the measured IPP. The spherical harmonic model parameters are calculated by the weighted least squares method. Based on the Global Ionosphere Map (GIM) released by Center for Orbit Determination in Europe (CODE), the comparison of the vertical TEC value obtained from this present method with the modeling method only using BDS/GPS IPP data shows that a significant accuracy improvement of the area lacking the measured IPP has been obtained by the method in this paper.
