Paper on the evaluation of satellite observations with VLBI published

The installation of a VLBI transmitter on Galileo satellites would allow observing satellites besides quasars with VLBI telescopes. Three additional Dilution of Precision (DOP) factors were introduced which are representing the sensitivity of a satellite observation towards the components of the satellite position in the local orbital. These factors were used for evaluating observations to […]

Paper on Southern Intensives for UT1 determination published

The need for stimulating global geodetic measurements with southern observatories served as a powerful motivation to launch the Southern Intensive (SI) program in 2020. The competitiveness of these SI sessions with routinely operated Intensive sessions has now been demonstrated in a paper published in Earth, Planets and Space.

First IVS VGOS session successfully correlated at TU Wien

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 […]
