Short-term earth orientation parameters predictions by combination of the least-squares, AR model and Kalman filter

► We employ a combination of least squares (LS), AR model and Kalman filter (LS + AR + Kalman) in short-term prediction of the EOP. ► The LS + AR + Kalman method works better than the LS + AR model. ► LS + AR + Kalman shows general better results compared to the EOP PCC.
