The superconducting gravimeter achieves sensitivities of 10 –11 m·s −2 (one nanogal), approximately one trillionth (10 −12) of the Earth surface gravity. In a demonstration of the sensitivity of the superconducting gravimeter, Virtanen (2006), [ 8 ] describes how an instrument at Metsähovi, Finland, detected the gradual increase in ...

The Lunar Traverse Gravimeter was a lunar science experiment, deployed by astronauts on the lunar surface in 1972 as part of Apollo 17.The goal of the experiment was to use relative gravity measurements to infer potential attributes about the geological substrata near the Apollo 17 landing site.
George William Fullerton (March 7, 1923 – July 4, 2009) was a longtime associate of Leo Fender and, along with Fender and Dale Hyatt, a co-founder of G&L Musical Instruments.
