Absolute Measurements of Gravity

Abstract

The Institute of Geophysics & Planetary Physics (IGPP) has completed a two-phase three-year program of absolute gravity research and development. The development phase included modifications to an existing absolute gravity meter. Our goal was to incorporate state-of-the-art technology and portability while maintaining meter accuracy. The research phase included both field testing of the modified meter and the establishment of new absolute gravity sites. In particular, we were able to survey absolutely a series of closely spaced sites along existing calibration lines. Keywords: Absolute gravity meters; Gravity; Interferometers; Acceleration; Falling bodies; California; Free fall retroreflectors.
