IVS Combination Centre

The IVS Combination Centre was inaugurated by the International VLBI Service for Geodesy and Astrometry (IVS) Directing Board in October 2008 as a joint effort of the Federal Agency for Cartography and Geodesy (BKG) and the German Geodetic Research Institute (DGFI).
The tasks of this IVS Combination Centre include quality control and a timely combination of the session-based intermediate results of the IVS Analysis Centres into a final combination product (e.g., Earth Orientation Parameters, EOP). These combination results will be released as official IVS products. Furthermore, the IVS Combination Centre is also expected to contribute to the generation of the official IVS input to any ITRF activities.

Assigned Tasks at BKG

Analysis Centers

Analysis Centres produce series of Earth Orientation Parameters (EOP) as well as station coordinates and source positions in regular intervals. These individual series are combined by the IVS Combination Centre at BKG and sumbitted as official IVS products.
