Abstract. The paper presents the results of processing observations of the Global navigation satellite systems (GNSS) at the satellite-geodetic stations of the SAI MSU and the Geographical Faculty of the Lomonosov Moscow State University. Estimates are obtained for the displacement rate of the stations in the International terrestrial reference frame (ITRF), release 2008 and the fixed Eurasia frame. The results showed good data quality and coordinated movement of stations. At the same time, due to the smallness of displacement velocities, the use of the Eurasian reference system is not enough to study regional deformations. For stations on the Vorobiyovy Gory, anomalously high speeds of vertical movements were revealed, which, apparently, are due to the close proximity of observation points to the reservoir, and are also possibly related to the local geodynamic features of the northern slope of Teplostanskaya Upland.

Keywords: modern geodynamics, satellite geodesy, GNSS, modern movements of the Earth's crust, deep fault, lithosphere block.
