The daily movements of EUPOS®-Riga and LatPos permanent GNSS network stations have been studied. Reference stations from EUREF Permanent Network (EPN) have been used. The standard data sets were taken from IGS data base – ionosphere and troposphere parameters, satellite orbits, satellite clock corrections, as well as the Earth rotation parameters. The Bernese GPS Software allows the estimation of kinematic receiver coordinates. This feature has been applied and kinematic parameter estimation for EUPOS®-Riga and some LatPos stations has been carried out. Processing of mixed – kinematic and static, stations has been performed in the same solution. Eight EPN stations: JOZE, MDVJ, METS, PULK, RIGA, TORA, VIS0, VLNS, were fixed, i.e., static for datum definition in each kinematic network solution.
