For the first time, a member of the Higher Geodesy group in Vienna traveled to the Astronomical Data Analysis and Software System (ADASS) conference. This year, ADASS was hosted by the Netherlands in Groningen. Matthias Schartner presented his new VLBI scheduling software VieSched++. Have a look at the abstract.

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 […]
