Excursion to Geodetic Observatory in Wettzell (Bavaria)


In Novmeber 2008, th Chair of Precission Navigation and Positioning made an excursion to Wettzell (Bavarian Forest) for visiting the fundamental station. After a long time of planning and organization, a date was found and we went there from 20th November until 22nd November 2008. Altogether, ten students participated besides Prof. Roman Galas and Mr. Scholz. After a six hours lasting trip, we finally arrived late at night at our accommodation in Bad Kötzting, a little town about 5 km away from the station. Next day, the station and its different measuring systems were shown and explained to us during a several hours lasting guided tour.  General stuff about the station At first, Dr. Reiner Dassing presented the station and its history to us in a two hour lecture. The beginnings of this station go back to the year 1971. In these days, it was impossible to add a laser range measuring system to the satellite observation ward of the institute for applied geodesy in Kloppenheim (Taunus). In coordination with the responsible departments, an area in the Bavarian Forest was selected, over which a restricted area for planes was created. A parcel was selected which was rent firstly and developed cheaply for first projects. In the beginning, the station consisted only of a wooden shed with a mobile roof. Nowadays, the station comprises several facilities and measuring systems. The following systems were shown to us:

 ring laser
 superconducting gravimeter
 permanent GNSS receiver
 20 m radio telescope
 WLRS (Wettzell Laser Ranging System)
 time and frequency system
Following our visit of the fundamental station, we went back to Bad Kötzting. Here, we spent the evening together in a typical Bavarian guesthouse. Due to bad weather, we left Bad Kötzting very early next morning and arrived
