第八届绝对重力仪国际比对（ICAG-2009）和相关的相对重力运动（RGC 2009）于2009年7月至10月在国际计量局（BIPM）举行。总共有24个研究所、22台绝对重力仪和9台相对重力仪参加了国际重力学理事会/研究和地理学理事会的活动。在BIPM的微重力三维网格上进行了精确的绝对和相对重力测量以及精密水准测量。2009年的比较是第一次在国际计量委员会（CIPM）MRA（相互承认安排）下组织的国际计量委员会（CIPM）关键比较，这意味着结果将得到负责的政府组织的正式承认。因此，与早期活动相比，所使用的相对重力仪经过精心挑选，测量计划得到严格执行。从而提高了RGC 2009的质量和BIPM局部重力网的确定性。经过30年和连续八届ICAG，BIPM决定将其作用转移到国家计量研究所，尽管CIPM将继续作为ICAG组织关键比较。本文介绍了RGC 2009的背景，重力和重力垂直梯度的组织、数据处理和最终结果。本报告比以往各研资局的最后报告更为详细。
The 8th International Comparison of Absolute Gravimeters (ICAG-2009) and the associated Relative Gravity Campaign (RGC2009) took place at the Bureau International des Poids et Mesures (BIPM) between July and October 2009. Altogether 24 institutes with 22 absolute gravimeters and 9 relative gravimeters participated in the ICAG/RGC campaign. Accurate absolute and relative gravity measurements as well as precision levelling measurements were performed on the micro-gravity 3D-grid at the BIPM. The 2009 comparison was the first to be organized as a Comité International des Poids et Mesures (CIPM) metrological Key Comparison under the CIPM MRA (Mutual Recognition Arrangement), which means that the result will be officially recognized by the governmental organizations responsible. As a consequence, the relative gravimeters employed were carefully selected and the measurement schedules were rigorously enforced compared with earlier campaigns. Thus the quality of the RGC2009 and the determination of the BIPM local gravity network were improved. After 30 years and eight successive ICAGs, the BIPM has decided to transfer its role to the national metrological institutes, although the CIPM will continue to organize the key comparison as ICAGs. The background to the RGC2009, and the organization, data processing and final results of the gravity and vertical gravity gradients, are presented in this paper. This report is more detailed than previous final reports of the RGCs.
