The VLBI core in radio loud AGNs

, 2001
We present statistical results on VLBI cores from large VLBI samples at C, L and S/X bands. Most of the results are consistent with the inhomogeneous jet model.

New Progress in VLBI tracking of GNSS satellites at GFZ

, 2014
The topic VLBI tracking of GNSS satellites has emerged lately as a new way for linking of the dynamic reference frame realized by GNSS satellites to the ICRF.

In-depth analysis of schedules optimized for certain VLBI experiments using VieSched++

, 2019
Scheduling is an integral part of every VLBI experiment and, at this stage, already determines the geometric stability of the final solution. To increase the quality of the schedule, the TU Wien scheduling concept consists of two steps.
