Abstract
In this chapter, the dynamic effects of the Earth pole motion in the celestial-mechanical problem statement as the “deformable Earth–Moon problem in the gravitational field of the Sun” are discussed. The orbits of the Moon and the Earth–Moon barycenter are assumed as known and given ones. Combination harmonics in the Earth pole motion are found and their connection with perturbations caused by the Moon’s orbit precession is shown. Applying a numerical–analytical approach, the additional components of the Earth pole motion model were determined in an explicit form.
