Аnnotation: Results of GNSS observations (global navigation satellite system GPS/GLONASS) in 2006-2018 in the study the modern intraplate geodynamics of North-West of Russian Federation are analyzed. In the study of modern movements and deformations of the earth's crust, the data of repeated satellite measurements carried out by the staff of the IFZ RAS in Karelia, Leningrad region, as well as measurements from 20 permanent stations of the International geodynamic network were used. In addition, the data obtained at the new geodynamic polygon located in the Kandalaksha Bay area, where several cycles of repeated measurements have been carried out since its foundation in 2015, are considered. Repeated GNSS measurements confirmed that dome-shaped lifting, confined to the Baltic shield, continues with a velocity 10.4 mm/year. Within the Russian part of the territory the rate of uplifting reaches 6 mm/year. Horizontal displacements of GNSS stations in the ITRF have a North-East direction and average velocities (according to approximated data for 2006-2018) from 19.9 mm/year in the north to 23.9 mm/year in the south. The deformation field of the region is non-homogeneous, the extended compression and stretching zones replace each other, with values from (-0.8)×10
