摘要	The radio wave used in communications at distance and navigation by satellite is affected by the ionosphere. Therefore the study on the total electron content (TEC) in the ionosphere is very important. There are some prediction models of the ionosphere. But the accuracy of prediction by them is 50% similar to 60% only. A new ionosphere model to predict total electron content is proposed. In this model the total electron content given by IGS at each node of grid is fitted by spherical-harmonic expansion. The fitted coefficients at different times form the time series, which are predicted by the ARMA(p, q) model so as that the prediction of total electron content in the ionosphere is implemented. The TEC data of IGS in 2004 and 2005 are analyzed by our method in order to predict the TEC in the geographic frame. The relative accuracy of prediction for 5 days obtained by our method is about 90%.
