K. Boerger Comparison of European network solutions ABSTRACT Comparison of European network solutions In the last years European VLBI arrived at high efficiency. The number of stations increased and the frequency of campaigns was forced. The accuracy of station coordinates is about several millimeters and the formal errors of the horizontal motions are less than 1 mm per year. In Europe different groups analyse the observed data and provide results, which should in fact converge. In order to investigate this question an analysis was performed, which compares the analysis strategies and the results of the different groups in order to assess the consequences of the individual approaches. ----------------------------------------------------------------------- In Proceedings of the 13th Working Meeting on European VLBI for Geodesy and Astrometry, Viechtach, 1999 Keywords: VLBI, europe-campaigns, comparison, data analysis
