Permanent and periodic satellite GPS observations in SW Poland are realized since 1996. The results of these observations are used for the earth crust surface movements determination. Values of the movement velocities are significant for horizontal as well as vertical components. The vertical movements determined by GPS were compared with the vertical movements obtained by repeated leveling measurements, performed in the 50'ties, 70'ties and 90'ties of the 20th Century. The calculated movements are discussed in relation to tectonics in the paper.

The characteristics of geodynamic investigations in the Eastern Sudetes and the Fore-Sudetic Block region during the 1993-2003 period are presented. The investigations included repeated GPS, gravimetric and other observations realized in three local research areas and a regional network. The local research networks have been integrated into the regional network through selected points. The regional network has been connected to the permanent stations network EPN/IGS. This has allowed calculation of the points' velocities in a uniform reference frame ITRF2000. The calculated movement parameters of points have been the basis for estimating the kinematics of tectonic structures including gravity changes. The results have confirmed recent activity of the young tectonic structures in research region.
