As a new Analysis Center (AC) of the International Very Long Baseline Interferometry (VLBI) Service for Geodesy and Astrometry (IVS) we have determined a VLBI time series solution which is meant to serve as an input to the upcoming International Terrestrial Reference Frame realization ITRF2013.In addition,it will be the basis for the GFZ VLBI global solution.The first version of the global solution will be released soon and later it will be updated on a regular time interval.
