Abstract：Based on the nonlinear and nonstationary characteristics of total electric contents time series，the combination of SSA method and ARMA model was proposed to predict TEC.In the combination，ARMA model is used to predict the data which had been decomposed and filtered by SSA method，and the predicted value of each component is overlaid.The results calculated by the combination for 2010TEC data show that the mean relative precision of TEC prediction for 5 days is 92% by the combination，and the accuracy is improved of 4%，comparing with individual ARMA method.
