New permanent GNSS networks in the Czech Republic and their use in geosciences

In this article the two permanent GNSS networks in the Czech Republic are shortly described. The first one - Czech Positioning System - CZEPOS is being established by the national surveying and mapping authority - Land Survey Office. It is the network of reference slations mainly destinated for users from geodetic and navigation community. The second one is the research and experimental GNSS network - VESOG. This network is jointly created by research and academic institutions. Both networks will be connected. The data from all stations will be usable for geoscientific applications: detected position changes will serve for interpretations in geodynamics, near-real-time data will be used in projects of GPS wound-based meteorology (e.g. TOUGH), real-time data streams will be used for real-time rositioning in the frame of the EUREF-IP project.
