%X The GM(1,1)model was used for the dynamic prediction of polar motion parameters.To further improve the forecasting accuracy the intercept correction theory is introduced,and a new intercept correction method is proposed to adjust the forecasting results.The results show that GM(1,1)model can well be used for polar motion prediction,and the forecasting accuracy is effectually inproved with the new intercept correction method.
