Time series of tropospheric parameters by analysing of GNSS observations from a global IGS (International GNSS Service) network and regional networks - EPN (EUREF Permanent Network) in Europe and VESOG, GEONAS and CZEPOS in Czech Republic.

Network of Permanent GNSS Stations in Greece operated by the Research Institute of Geodesy, Topography and Cartography, Geodetic Observatory Pecny and the Charles University in Prague, Faculty of Mathematics and Physics, Department of Geophysics, in close cooperation with the Seismological Laboratory of University of Patras

Research and experimental network of permanent GNSS stations operated by the Research Institute of Geodesy, Topography and Cartography, Geodetic Observatory Pecny in cooperation with more academic and research institutions in the Czech Republic: Brno University of Technology, Palacky University of Olomouc, Technical University of Ostrava, West-Bohemia University in Pilsen, Institute for atmospehric physics CAS, Military Geography and Hydrometeorologic Office Dobruska.

Coordinate time series based on analysing GNSS observations from a subset of EPN (EUREF Permanent Network) or CZECH - GNSS networks in Czech Republic - VESOG, GEONAS, CZEPOS. It includes daily solutions from EUREF processing or EUREF reanalyses.

Relative superconducting gravimeter OSG-050 manufactured by GWR Instruments, Inc. USA. It provides continuous measurement of gravity variations with sampling rate of 1 sec at the gravimetric station Pecny since 2007. Data are distribued to IGETS (International Geodynamics and Earth Tide Service).

Repeated measurements of gravity acceleration at five absolute gravity stations in the Czech Republic have been carried out by absolute gravimeters FG5 No. 215 and FG5X No. 251 manufactured by Micro-g LaCoste, Inc. USA. Data are distributed to AGrav database.

Orbits of GNSS satellites and Earth rotation parameters based on analysis of GNSS observations from a global network of IGS (International GNSS Service) stations in rapid or ultra-rapid processing mode.
