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 […]

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.

On June 30, 2022, Jakob Gruber successfully defended his PhD thesis on Raw Data Simulation and Correlation of VLBI data. After the presentation of his thesis, Jakob withstood the difficult questions from Axel Nothnagel, Jamie McCallum and Johannes Böhm. Congratulations and thanks for the nice party in Hof3! @tu_wien @geodepartment @j_boehm72

On June 20, the excursion to the Geodetic Observatory Wettzell organised by the Vienna VLBI Group took place. This year, 34 students and 7 staff members participated in the trip to the Bavarian Forest. At the observatory, we were able to inspect three VLBI antennas, two SLR/LLR systems, many GNSS antennas and a DORIS beacon. […]
