For the first time, a 24h VGOS session of the International VLBI Service for Geodesy and Astrometry (IVS) was correlated at TU Wien. Eight globally distributed radio telescopes participated in session VO1021 on January 21, 2021, each observing quasars with a data rate of 8 Gbit/s. In total, more than 220 TByte had to be […]
