The phrase "a gravity gradient of" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or geophysics when discussing variations in gravitational force over a distance.
Example: "The satellite's sensors detected a gravity gradient of 0.1 mGal, indicating a significant geological feature below the surface."
Alternatives: "a gravitational gradient of" or "a gradient in gravity".
This type of survey observes a gravity gradient tensor consisting of six components of three-dimensional (3-D) gradients of gravitation by a causative body and has higher sensitivity than gravity surveys.
Fedi et al. (2005) show the fine image of the structural setting in the southern Apennines which is obtained from analyzing several single components of a gravity gradient tensor.
For instance, the NIST compensates for Earth's gravity gradient of 309µGal per meter when the elevation of the center of the gravimeter differs from that of the nearby test mass in the watt balance; a change in the weight of a one-kilogram test mass that equates to about 316µg/m.
The attitude determination and control system (ADCS) on CX-I uses a unique gravity gradient boom design constructed of tape measure material.
In order to better retrieve coseismic gravitational signals, we apply a northern gravity gradient approach with the filter of spatial averaging and without destriping.
In the case of STEP, gravity gradient forces of magnitude 10−7 g act on the superfluid helium at twice orbital frequency.
The coseismic northern gravity gradient changes of Tohoku-Oki earthquake are extracted from the monthly data of April 2011, which reveal a positive-negative-positive spatial pattern and agree with the model prediction.
(d) Northern gravity gradient changes of April 2011 with respect to the 4-year mean field, with 300 km Gaussian smoothing and without destriping.
(f) Northern gravity gradient changes of February 2011 with respect to the 4-year mean field, with 300 km Gaussian smoothing and without destriping.
The observation indicates that the presence of gravity gradient is a key issue for the growth of ZnO nanowire arrays.
