Gravity gradiometry navigation
WebJan 1, 2014 · Gravity gradiometry is over 110 years old and it offers a rich perspective of the Earth’s external gravitational field as generated by its internal mass density structure. Like the measurement of gravity, gradiometry is used to make both qualitative and quantitative interpretations of the Earth’s near subsurface interior. WebAtom gravimeters use locked lasers to manipulate atoms to achieve high-precision gravity measurements. Frequency modulation spectroscopy (FMS) is an accurate method of optical heterodyne spectroscopy, capable of the sensitive and rapid frequency locking of the laser. Because of the effective absorption coefficient, Doppler broadening and susceptibility …
