Abstract

The RT-22 radio telescope in Katsiveli (Crimea) actively participates in the international projects on the support of space-time reference systems for the monitoring of global changes and precise navigation in space. One of such projects has been elaborated at the Department for Investigations in Germany (Deutshe Forschungsgemeinschaft – DFG) with the aim of providing a quasi-inertial reference system realized by the coordinated position of a quasar and terrestrial reference frame based on the general set of parameters and, particularly, on homogeneous geophysical models “Ocean”, “Atmosphere” and “Hydrology”. For the analysis of vertical deformations of the Earth in Katsiveli (Crimea) we used data about corrections to vertical deformations of the Earth calculated according to the model “Atmosphere”. The basic result of the analysis is an extraction and analytical description of the periodic trend. The amplitude of the detected annual wave is 3.3 ± 0.5 mm.
