000193254 5203_ $$9eng$$aScientists from metrology and geosciences agreed on a proposal to base a new absolute gravity reference upon repeated instrument comparisons under metrological rules for traceability to SI quantities. In a strategy paper, which originated from the lively discussion of a mixed working group in metrology and geodesy with the objective to define and harmonize the measurements at the highest accuracy level, it was proposed to continue the comparisons under the International Committee for Weights and Measures (CIPM) every four years at alternating locations with the aim to distribute comparison results over a global network of carefully observed gravity reference and comparison sites. Their gravity variations are recorded by a combination of repeated absolute gravity measurements and continuously operating superconducting gravimeters. The results of comparisons and the gravity variations of the reference stations will be documented in a registry, part of the AGrav database, maintained jointly by the International Gravimetric Bureau (BGI) and the Federal Agency for Cartography and Geodesy (BKG). The implementation of the new gravity reference system will be based upon the international standards and conventions of the IAG. During the IUGG General Assembly in Prague 2015, the IAG adopted Resolution No. 2 and initiated the Establishment of a Global Absolute Gravity Reference System.
