German Repeat Station Surveys (until 2012)

The German geomagnetic repeat station network consisted of 45 points out of a denser network from former ground vector surveys. Regular repeat station surveys started in 1992 and were carried out every 4 years. The measurements were taken by a fluxgate theodolite (D, I) and a proton magnetometer (F). A variometer close to the point of observation was used for proper data reduction to the epoch.

The measurements and production of magnetic charts has been a joint task of the three German Geomagnetic Observatories Niemegk, Wingst (both Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum) and Fürstenfeldbruck (Ludwig-Maximilians-Universität München). With the adoption of Wingst observatory by GFZ in 2000 these tasks have been overtaken by Niemegk observatory.

The repeat station surveys were terminated in 2013. The data of the magnetic observatories and satellite missions are sufficient to map the main field and its secular vatiation over Germany.
