“…Gravity gradient signals can provide the small-scale features of sources, such as oil, gas and mineral resources buried in the ground [ 2 ]. As a high-accuracy, high-resolution signal of the gravity field, the gravity gradient has an important role in hydrocarbon or mineral exploration, geophysics and inertial navigation [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. With the Euler deconvolution as an example, more detailed information and more accurate results could be obtained through gravity gradient data [ 6 ].…”
