Abstract

In this paper, I summarize the main applications and history of precision measurement of Earth gravity (g). Two common types of gravimeters are discussed: the relative, static, spring type and the dynamic, free-fall, absolute gravimeter. In particular, the design, construction, and performance of our latest free-fall gravimeters (MPG-2) are presented in detail. Various sources of error have to be carefully considered and removed to reach a precision at the micro-Gal (10−9 g) level. The paper is a summary of the talk given at the Enrico Fermi School during the summer of 2007.
