The coefficients of the Global Gravitational Models(GGMs) define the external gravitational field of the Earth.In many geoscience applications and gravity interpretations these coefficients are routin
In Global Navigation Satellite Systems(GNSS) positioning,one often tries to establish a mathematic model to capture the systematic behaviors of observations as much as possible.However,the observation
For comparison of noise levels between superconducting gravimeters(SGs) and gPhone gravimeters, we conducted an experiment in which we carried out co-located observations of gravity changes by the sam
