Precision Measurement of the Newtonian Gravitational Constant Using Cold Atoms

, 2014
About 300 experiments have tried to determine the value of the Newtonian gravitational constant, G, so far, but large discrepancies in the results have made it impossible to know its value precisely.

Mathematic Model And Error Analysis of Moving-base Rotating Accelerometer Gravity Gradiometer

, 2019
In moving-base gravity gradiometry, accelerometer mounting errors and mismatch cause a rotating accelerometer gravity gradiometer (RAGG) to besusceptible to its own motion. In this study, we comprehensively consider accelerometer mounting errors, circuit

The Gravity Gradiometer Survey System (GGSS)

Eos, Transactions American Geophysical Union, 1988
The art and science of measuring Earth's gravity field has acquired a new dimension over the last decade as moving base systems were developed to complement or even replace the tried and true static gravimeter. The clear motivation behind these developments is efficiency.

From the time-wise to space-wise GOCE observables [PDF]

Advances in Geosciences, 2003
The observables of the GOCE three-axis gradiometer are taken in time, along the orbit and, in the timewise proposal, filtered to stay in the measurement bandwidth, i.e. in the frequency interval between 0.005 and 0.1Hz.
