To assess the characteristics of recent movements of territory of Ladoga-Onega region here we considered GPS measurements carried out by the staff of IPE RAS and GAO RAS, as well as recent results of I and II classes leveling, water level observations in lakes and satellite altimetry data. The velocities of horizontal and vertical movements in Ladoga-Onega region are revealed. Reliability of the results is confirmed by the control velocities of horizontal and vertical motion as the nearest points of a European network, and the Russian network, that coincide with the standard rates in the frames of the Eurasian plate. The observed elevation of points in Karelia by the GPS data differs from the results of leveling and the values of the velocities of depression, according to the water level observations of Ladoga lake and, especially, satellite altimetry.
Keywords: Baltic Shield, Ladoga, Onega, satellite technology, recent movements, horizontal velocity, vertical velocity, strain, velocity
