摘要
当前负责重力测量的国际组织CCM-WGG和SGCAG决定今后将举办绝对重力仪区域性国际比对,并开始着手在世界范围内选择区域性国际比对点.CCM-WGG和SGCAG制定了国际比对的技术规范,讨论了绝对重力仪比对申请为关键性国际比对的议案.本文将介绍相关的国际情况以及中国计量科学研究院在这方面所做的工作.本文还将介绍2005年第七次国际绝对重力仪比对的情况和初步结果.
CCM-WGG in collaboration with the SGCAG is in charge of international affairs about gravity measurement. CCM-WGG and SGCAG have decided to organize regional international comparison of absolute gravimeters and started searching the sites for the comparison around the world . CCM-WGG and SGCAG also have established the technical protocol for comparison of absolute gravimeters and discussed the proposal on applying absolute gravimeter comparison as a key comparison. This paper introduces the international condition and our work about this. This paper also introduces the status and preliminary results on 7th absolute gravimeter comparison in 2005.
