1 The German Repeat Station Survey 2006 M. Korte and M. Fredow, GeoForschungsZentrum Potsdam In 2006 a complete survey of the German repeat station network was carried out. We followed the procedure, established in the previous years, with first and second order stations. At the 12 first order stations a portable variometer is set up for optimal correction of external and induced field influences. The variometer is kept recording there for a minimum of 3 days, and long enough to include quiet night time values. Meanwhile the surrounding second order stations are surveyed, which are generally no more than 150 km away. Here, we present the first results from the 2006 survey.
