CONSORTIUM FOR CENTRAL EUROPEAN GPS GEODYNAMIC REFERENCE NETWORK (CEGRN CONSORTIUM)

Abstract

Application of GPS measurement for monitoring tectonic processes in Central Europe on a regional scale was initiated in 1993 in the framework of the “Central Europe Regional Geodynamics Project„, or CERGOP. The initial basic reference network (CEGRN) consisted of 31 sites, established in 1994 and monitored regularly ever since. These sites already have spanned7 epochs of monitoring results over 9 years. CEGRN was extended in 1998 and presently consists of 62 official sites of which about 50% are permanently operating stations. The additional 31 sites monitored since 1999 span 3 epochs of monitoring results over 4 years. Densification of CEGRN up to about 100 sites is foreseen in the framework of the CERGOP-2/Environment project, supported within the EU 5^th FP in the years 2003-2006. The CEGRN network meets the highest quality standards and is outstanding in the areas of homogeneity and long time series of measurements. A consortium of institutes was formally established in 2001 for securing the long-term operation of CEGRN.
