Summary:According to the respective characteristics of polar motion and length of day, combining LS and AR model, a suitable prediction model for the Earth Rotation Parameter(ERP) was builded. In order to reduce the strong correlation, the difference before establishing AR model was down and ERP 1-10 days were predicted. The results show that the prediction accuracy has reached an international leading level.
