Аннотация: The Earth’s mass redistribution generates temporal variations of the coefficients of geopotential, of the components of the tensor of inertia and as result leads to the variation of the orientation in its principal axis of inertia. The purpose of this paper is to study the motion of the Earth’s principal axis of inertia C&tC due to tidal deformations from the Moon’s and Sun’s attraction, and also due to its rotational deformations. To obtain corresponding corrections to values of the geopotential, coefficients ase determined with respect to the reference system CtqC. One investigation of this problem was made by Bursa (1983). In this paper we will use Ferrandiz and Getino’s paper (1993) in which in details of the periodic tidal variations of the coefficients of the second harmonic of the gopotential were described. The authors use the classical model of the Earth with an elastic mantle (model Takeuchi 2). For a description of the rotational deformations of the second harmonic of the geopotential in this paper classical expressions for the rotational deformations of the component of the tensor inertia are used. This investigation has an important significance for the determination of the main reference systems for different geodynamical studies, in satellite dynamics and for the theory of the rotation of the deformable Earth.
