FG 5 -202绝对重力仪与C 021超导重力仪并排进行了连续测量。一种是在47天内完全同时在两种文书上登记。该原始实验允许通过两组数据之间的简单线性回归在时域中或通过比较地球潮汐分析在频域中校准超导重力仪。校准因子的精度优于0.1%。此外，这是第一次，一个精确的和成功的潮汐分析绝对重力仪观测已获得。两组数据之间的比较也显示了与超导重力仪的稳定性和绝对重力仪的相对精度有关的有趣的特征。
Continuous measurements with the FG5-202 absolute gravity meter were made at Membach side by side with the C021 superconducting gravimeter. One disposes of 47 days of exactly simultaneous registrations with both instruments. This original experiment allows to calibrate the superconducting gravimeter either in the time domain by a simple linear regression between the two sets of data or in the frequency domain by comparing the Earth tide analyses. The accuracy on the calibration factor is better than 0.1%. Moreover, this is the first time that a precise and successful tidal analysis of absolute gravimeter observations has been obtained. The comparison between the two sets of data shows also interesting features related to the stability of the superconducting gravimeter and to the relative accuracy of the absolute gravity meter.
