ln a 1992 one of the first local geodynamic networks in Czech republic was established in czech-polish cooperation - the Sneźnik network. The network was designed as a model for testing of methodical and technological procedures for repeated satellite and classical geodetic measurements. Since 1992 several campaigns of GPS, EDM, levelling, gravimetric, astronomical and other measurements bad been carried out in the network within previous projects., Brno University of Technology had organized observation activities and carried out the measurements and processing of all campaigns in Czech part of the network. In years 1996 - 1998 the works in scope of the research project oriented on problems of the common processing of GPS and terrestrial measurements were carried out here in cooperation of TU Brno and Research Institute of Geodesy, Topography and Cartography Zdiby - Geodetic Observatory Pecny. This contribution gives overall history of measurements and describes the time evolution of the network points positions in time span of 8 years, estimated on ground of GPS data.
