Micro-gravity investigations for the LNE watt balance project

Abstract : We report on a micro-gravity survey of the laboratories where the LNE's watt balance experiment is being conducted, including the characterization of the Scintrex CG-5 relative gravimeter used for this study. The results of the survey are compared with a model of the gravity field generated by the local mass distribution. The ultimate goal is to transfer an absolute measurement of g from one room to another with minimal uncertainty.
