Bonn Correlator Status

Autor: Choi, Yoon Kyung, Bernhart, Simone, Rottmann, Helge, Wagner, Jan

We report on the status of the Bonn Correlation Center focusing on geodesy. The Bonn Distributed FX (DiFX) correlator is operated jointly by the Max Planck Institute for Radio As- tronomy (MPIfR) in Bonn and the Federal Agency for Cartography and Geo

The next-generation VLBI system, known as the VLBI Global Observing System (VGOS), is currently being deployed worldwide to replace the legacy S/X VLBI system. The latter has been operating for geodesy and astrometry during the last four decades and

International audience; Analysis of VLBI records of distant radio source signals allows to determine the proper motions of the extragalactic objects with an accuracy of a hundred microseconds of arc per year (muas/yr). Such an accuracy is sufficient
