The Gedex gravity gradiometer (AKA High-Definition Airborne Gravity Gradiometer, HD-AGG) is also a superconducting OQR-type gravity gradiometer, based on technology developed at the University of Maryland. iCORUS gravity gradiometer The iCORUS gravity gradiometer is a strapdown airborne gravity gradiometer, based on technology developed at iMAR ...
Gravity is usually measured in units of acceleration.In the SI system of units, the standard unit of acceleration is metres per second squared (m/s 2).Other units include the cgs gal (sometimes known as a galileo, in either case with symbol Gal), which equals 1 centimetre per second squared, and the g (g n), equal to 9.80665 m/s 2.
Axial gradiometer. This device consists of two magnetometers placed in series (i.e., one above the other). The result coming from the device is the difference in magnetic flux at that point in space, in other words, the result is the difference between what each of the magnetometers detects. Biaxial gradiometer. This device consists of three ...
A gravity map is a map that depicts gravity measurements across an area of space, which are typically obtained via gravimetry. Gravity maps are an extension of the field of geodynamics . Readings are typically taken at regular intervals for surface analysis on Earth . [ 1 ]
An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction. It is also known as a tilt indicator, tilt sensor, tilt meter, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator.
Direct observation of gravitational waves, which commenced with the detection of an event by LIGO in 2015, [1] plays a key role in gravitational wave astronomy.LIGO has been involved in all subsequent detections to date, with Virgo joining in August 2017.
The gravity gradient (components of the gravity field) is measured using a spinning wheel with accelerometers also called as the gravity gradiometer. [4] The instrument is positioned in different orientations to measure the respective component of gravitational field. The values of gravitational gradient tensors are calculated and analyzed.
The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) was the first of ESA's Living Planet Programme heavy satellites intended to map in unprecedented detail the Earth's gravity field. The spacecraft's primary instrumentation was a highly sensitive gravity gradiometer consisting of three pairs of accelerometers which measured ...
