Abstract: Since 2006 the International GNSS Service (IGS) started with reprocessing of all IGS products (Steigenberger et al., 2006; Ferland, 2010) according newly adopted models and reference frame. The resulting reprocessed products are of superior quality and homogeneous through the whole time span. Moreover the IGS re-processing made available all the products also for the period before year 2000 when IGS originally started to provide them. The availability of those products was the main motivation for a comprehensive reprocessing of all GNSS data from the Local Geodynamic Sněžník Network from the period between 1997 and 2011. All calculations were performed in the Bernese GPS software 5.0. The absolute method of Precise Point Positioning (PPP) was used for the first time within the network providing interesting results. The main evaluation of recent movement tendencies was done using common relative method where the nearest IGS points were used as reference points.
