Furthermore, it is making essential contributions to the determination of the scale of the International Terrestrial Reference Frame (ITRF). Based on a Memorandum of Understanding between TU Wien and the Federal Office of Metrology and Surveying (BEV), a Vienna Analysis Center (VIE) of the International VLBI Service for Geodesy and Astrometry (IVS) is jointly run by both organizations. The main focus of these activities is on the routine determination of Earth orientation parameters as well as the estimation of global reference frames.
