| Abstract |
In the framework of the celestial-mechanical approach, a long-period forecasting model of the pole motion is developed, taking into account perturbations from the Sun and the Moon with periods of one year and 18.61 years, respectively. The refined model takes into account the dynamic effects of the spatial motion of the Earth-Moon system in the oscillatory process of the Earth's pole. Using numerical-analytical modeling, the possibilities of identifying the parameters of the Earth's pole oscillation and approximating the developed refined model to real trajectory measurements are considered. Estimates of the accuracy of forecasting the motion of the pole are given taking into account additional terms caused by the lunar perturbation. |
