LitPOS (Lithuanian Positioning System), the network of continuously operating GNSS (Global Navigation Satellite System) stations, became operational in July 2007. It provides data both for real-time and post-processing applications. LitPOS stations cover the whole territory of Lithuania. There are 31 of LitPOS GNSS stations in total network. Also LitPOS network includes 3 ASGEUPOS (Poland) and 6 LATPOS (Latvia) stations. LitPOS network data processing and analysis of station’s velocities was done using Bernese 5.2, TSview and CATREF programs. Results of analysis show that North/East velocities of the LitPOS stations are very homogeneous what leads to the conclusion that there are no any significant horizontal deformations of Earth’s crust in the territory of Lithuania. Up components of LitPOS stations velocities fit very well to vertical movements of Earth’s crust as described by the land uplift models of Fennoscandia.
