Reference point determination with a new mathematical model at the 20 m VLBI radio telescope in Wettzell

A new mathematical model to estimate the International VLBI Service (IVS) reference point and additional parameters of a Very Long Baseline Interferometry (VLBI) radio telescope was developed by Lösler and Hennes (2008). To verify this analysis procedure a reference point determination was carried out on the 20m radio telescope at the “Fundamentalstation Wettzell” (Germany) from April to May 2008. This paper describes the terrestrial local survey, the analysis methodology and the results obtained, in particular the accuracy of the determination of the IVS reference point.
