Abstract :
The 2- and 8-GHz uncooled LNAs for VLBI radiometers were installed in Radio Telescope 22 at the Crimean Astrophysical Observatory (Simeyiz Station). The horizontal velocity of the Simeyiz Radio-Astronomical Station displacement was estimated using VLBI observations carried out under geodynamics programs. The station was found to move north-east at a rate of 2.8±0.9 mm/yr relative to the Eurasian tectonic plate considered as rigid.
