The regional key comparison of absolute gravimeters, EURAMET.M.G-K3 and the simultaneously organized additional comparison, was held in Germany at the Geodetic Observatory Wettzell of the German Federal Agency for Cartography and Geodesy in the spring of 2018.Here we present the list of the participants who actually performed measurements during the comparison, the data submitted by the operators as well as the results of the determination of the gravity as a function of height at the comparison sites. The measurement strategy is briefly discussed and the results of the data harmonization is documented. Finally, the results of the constrained least squares adjustment are presented including the degrees of equivalence of each gravimeter and the key comparison reference values.Main text To reach the main text of this paper, click on Final Report.

EURAMET.MG-K3绝对重力仪区域对比最终报告

绝对重力仪 EURAMET.MG-K3 的区域重点比较和同时组织的附加比较于 2018 年春季在德国联邦制图和大地测量局的测地观测站 Wettzell 举行。在比较期间实际进行测量的参与者、操作员提交的数据以及在比较地点确定重力作为高度函数的结果。简要讨论了测量策略，并记录了数据协调的结果。最后给出了约束最小二乘平差的结果，包括各重力仪的等效度和关键比较参考值。正文 点击Final Report进入本文正文。
