Gravity gradiometry is the study and measurement of variations (anomalies) in the Earth's gravity field. The gravity gradient tensor is the spatial rate of change of gravitational acceleration; as acceleration is a vector quantity, with magnitude and three-dimensional direction, the full gravity gradient is a 3x3 … See more Gravity measurements are a reflection of the earth's gravitational attraction, its centripetal force, tidal accelerations due to the sun, moon, and planets, and other applied forces. Gravity gradiometers measure the spatial … See more The derivative measurement sacrifices the overall energy in the signal, but significantly reduces the noise due to motional disturbance. On a moving platform, the … See more Lockheed Martin gravity gradiometers During the 1970s, as an executive in the US Dept. of Defense, John Brett initiated the development of the gravity gradiometer to support the Trident 2 system. A committee was commissioned to seek commercial … See more • Advances and Challenges in the Development and Deployment of Gravity Gradiometer Systems • GOCE mission payload See more Being the derivatives of gravity, the spectral power of gravity gradient signals is pushed to higher frequencies.
