This week, Matthias Schartner is visiting the VLBI group of the NASA Goddard Space Flight Center in Maryland, USA. The main purpose of this trip to demonstrate and teach how to use VieSched++ and VieVS together to generate high-quality VLBI schedules and Monte-Carlo simulations. Additionally, several other people from USNO and Haystack (MIT) took the […]

Today we visited the Westerbork Synthesis Radio Telescope (WSRF) and the Low Frequency Array (LOFAR) as part of the ADASS2019 conference. Especially LOFAR was very interesting since it is a very innovative new kind of telescope. Although it does not look very fancy, the science which can be done by LOFAR is outstanding. It observes […]

On September 10, 2019, Markus Mikschi presented his bachelor thesis on the integration of length-of-day values for the determination of UT1. Depending on the calibration, it is possible to achieve an accuracy of 40 microseconds after a week. It should also be noted here, that his presentation was the last one in our “old meeting […]
