在过去的几年里，德国联邦航空航天局(BKG)的超导重力仪通过与绝对重力测量进行了比较，进行了几次校准。对所有测量过程进行平均，得到了稳定的结果，误差在1 nm S 2N量级。其中三台仪器也用平台法进行了校准。该方法的内部精度提高了约一个数量级。然而，两种不同的校准方法的结果存在差异，其原因尚不清楚。
In the last years the superconducting gravimeters of the Bundesamt fur Kartographie and Geodasie (BKG) have been calibrated several times by comparison with absolute gravity measurements. Averaging over all measuring campaigns, stable results with errors in the order of 1 nm s 2N are reached. Three of the instruments were also calibrated by the platform method. The internal accuracy of this method is higher by about one order of magnitude. However, there are discrepancies between the results of the two different calibration methods, the origin of which is still not clear.
