The problem of motion, relative to the center of mass, of a satellite rotating around the center of gravity over an elliptical orbit, is studied. The satellite consists of axisymmetric solid and viscoelastic sections, with the viscoelastic section be

A model for the non-uniform axial rotation of the Earth is studied using a celestial-mechanical approach and numerical simulations. The application of an approximate model containing a small number of parameters to predict variations of the axial rot

Based on the model of a viscoelastic rigid body for the deformable Earth, we investigate the behavior of the main component of the perturbed Earth pole oscillation process, the Chandler wobble. An amplitude- frequency analysis of the perturbed Chandl

Based on the dynamical Euler-Liouville equations, we consider a numerical-analytical model of the Earth pole oscillations in the first approximation under the gravitational tidal forces from the Sun and the Moon. The dynamics of the Earth pole motion

Effects of fluctuational dissipative perturbations on the Earth’s polar motion due to random components of the centrifugal potential are studied using a numerical-analytical approach. A combined model for the polar fluctuations is used to take into

Based on a numerical-analytical model of the terrestrial pole oscillations, we investigate the effects of fluctuation-dissipation perturbations due to the pole tide. We consider the fluctuation perturbations at a frequency close to the Chandler one u

The necessity of taking many force components disturbing spacecraft (SC) orbits into account is demonstrated for the example of forecasts of GLONASS ephemerides. The disturbances of SCs in high-earth orbits (HEO) and low-earth orbits (LEO) are system

The fine dynamic effects that make it possible to improve the accuracy of predicting the trajectory of pole motion are revealed by using a numerically analytical approach in modeling the pole oscillatory motion, the key component of which is the Chan
