Description
Summary:Using a new version of the QUASAR domestic multifunction software package, we have simultaneously processed all of the available VLBI observations performed on global networks of stations over the period 1979–2009. New improved and extended versions of the international reference systems of coordinates of extragalactic radio sources and ground-based VLBI stations and a new independent series of Earth orientation parameters have been obtained. Analysis of the accuracy of these results shows that they are at the level of the best determinations at national and international VLBI data analysis centers.
