Continuing the improved, bi-annual repeat station surveys in Germany started in 2000, measurements have been carried out at all our 43 stations between April and October 2010. A local variometer is used at first order stations, and second order stations, no further than 150 km away from the variometer sites, are surveyed while the variometer is recording for a couple of days. We present results from the 2010 German repeat station survey and the secular variation between 2008 and 2010 determined from the consecutive surveys. In the 2008 survey, one station turned out to be hardly useable anymore and a substitute station nearby was established in 2009. However, it was still possible to do measurements at both original and substitute station in 2009 and 2010. We also report on the efforts and results to re-locate this station.
