CzechGeo / EPOS is the system of geophysical observatations performed by geoscience institutions of the Czech Republic. The backbone of CzecGeo is formed by permanent observatories (seismic, GPS, magnetic, gravimetric and geodynamic) involved in global networks which provide data in real time. Permanent observatoies are complemented by local stations in selected regions of interest. The third level of the observational system is formed by mobile stations which are deployed for repeated measuraments or field experiments within major international projects.
