GPS permanent stations situated in Central Europe region are systematically analyzed in order to investigate behaviour of long-term monitoring of horizontal position and ellipsoidal height. On the basis of data from more than 30 sites the quality of the station is evaluated. Stability of station is measured by variety of parameters: jumps and discontinuities of known but also of unknown origin, seasonal variations amplitudes and phases and diurnal coordinate variations. We estimate for each network station its main deterministic characteristics including identification of eventual jumps, their time of occurrence and magnitude, annual variations and site velocities. The set of criteria for defining "stable" permanent station is proposed.
