Finally, when the PAVL site situated in the centre of the HIGHLANDS geodynamic network was selected like the reference site (Fig.

Two 48-hour GPS epoch measurements on seven sites of the HIGHLANDS geodynamic network (BENE, HORI, NOSA, OSIK, PAVL, PEKL and ZABL) and two sites of the WEST SUDETEN network (BRAD, RUDN) were used to assess very preliminary site movement velocities.
