Evaluations of six years GPS epoch campaign measurements in the Tatra Mountains

The geodynamic investigation of the Tatra Mountains cmst movements is a local subproject of the CERGOP-2/Environment supported by the European Union. This contribution analyzes repeated epoch measurements performed in a special GPS network in order to investigate tectonic motions within the Tatra Mountains region. This GPS network was established in 1998 and consists of 11 sites, 7 in Slovak Republic and 4 in Poland. The size of the investigated area is approximately 40 km by 60 km with maximum relative height difference 1800 m between sites. Epoch measurements were performed annually from 1998 to 2003. Processing of all GPS campaigns was done using the Bernese software 4.2 with the standard procedure. All GPS campaigns were connecting to the nearest five IGS GPS permanent stations. For determination of the velocity vectors two models were used.
