Work-Package 7 of the CERGOP-2/Environment: geokinematical modelling and strain analysis activity report september 2004 - april 2005

Activities of WP 7 in the period September 2004 - April 2005 were devoted mainly to finalization of analysis of CEGRN'03 observing campaign and production of combined solution from relevant number of CERGOP processing centres. These results were then applied to estimation of the velocity field in the region using CEGRN epoch observations from 1994 to 2003. These new, more reliable velocities will serve as basis for subsequent strain analyses. Status of the CEGRN in 2003 comprising 71 stations is shown in Fig. 1. Among them are 35 permanent stations (including the IGS stations outside the Central Europe region which are used for referencing CEGRN to ITRF).
