In this paper a method of prediction of polar motion for up to 75 days ahead has been proposed. The method is based on least-squares collocation. Two models of the deterministic part of polar motion have been considered. The first numerical results are presented. The results shown in Table 2 prove that the proposed method provides higher accuracy of predictions than those given by IERS (1988).
