1997年11月在塞夫勒进行了第五次国际绝对重力仪相互比较。为了支持绝对测量，BGI第8工作组：绝对重力仪比较ICAG 97的相对网络也进行了相对重力仪活动。12台LaCoste和Romberg重力仪和1台Scintrex重力仪测量了每个点的绝对点和垂直重力梯度之间的联系。此外，还重新测量了1994年安装的校准基线，以检查或提供所有重力仪的校准系数。结果表明，Scintrex重力仪和LaCoste重力仪的单台仪器重力差的精度在3 ~ 8 μGal-1之间。该活动还用于比较校准重力仪静电反馈系统的不同方法。法兰克福的BKG校准平台安装在Sevres，其结果可以与校准线的结果进行比较。本文给出了1997年运动的结果。
In Sevres the fifth International Absolute Gravimeter Intercomparison was conducted in November 1997. In order to support the absolute measurements, the BGI Working Group 8: Relative Networks at Absolute Gravimeter Comparison ICAG97 conducted a relative gravimeter campaign as well. Twelve LaCoste and Romberg and one Scintrex gravimeters measured the connections between absolute points and vertical gravity gradients at each point. In addition the calibration baseline installed in 1994 was re-measured as well to check or provide calibration factors for all gravimeters. The results show that the accuracy for single instruments is in the range of 3 to 8 μGal 1 for a gravity difference, for both the Scintrex and the LaCoste gravimeters. The campaign was also used to intercompare different ways of calibrating the gravimeter electrostatic feedback systems. The calibration platform of BKG, Frankfurt, was installed in Sevres and the results can be compared to that of the calibration line. This paper gives results for the 1997 campaign.
