The new FG5 absolute gravimeter has a design goal accuracy of 1 μGal and represents the most recent of a series of gravimeters inspired by advances in gravimeter design by J. Faller at the Joint Institute for Laboratory Astrophysics (JILA) in Boulder, Colo. A 2-day workshop will be held in Boulder from March 22 to 23 to discuss current and future applications of absolute gravity (g). Details of the workshop appear at the end of this article. The instrument is based on the principle of interferometrically measuring the time and position of a weight falling in a vacuum, using a stabilized laser and an atomic clock [cf. Cook, 1967; Faller, 1963; Hammond, 1970; Zumberge, 1981; Niebauer, 1986].
