Ionized layer data analysis model construction method and terminal thereof

The invention discloses an ionosphere data analysis model construction method. The method comprises the following steps: S1, accurately determining an inter-frequency deviation between a satellite and a receiver based on an IGGDCB method; s2, establishing a local ionosphere TEC model based on a generalized trigonometric series function; s3, establishing a global ionosphere TEC model based on a spherical harmonic function; s4, calculating a grid point ionized layer VTEC based on an inter-station partitioning method; and S5, forecasting the global ionospheric TEC by adopting a least square combination maximum post-verification estimation method. According to the method, fine modeling, monitoring and forecasting of global scale and key area ionosphere changes are realized, and a global/area multi-scale ionosphere data analysis model is established, so that the fine monitoring and ionosphere threat early warning capabilities of a space ionosphere effect are greatly improved, and full guarantee is provided for ext
