The launch of gravity-dedicated satellite missions at the beginning of the new millennium led
to an accuracy improvement of global Earth gravity field models (GGMs). One of these …

The invariants of gravity (or gravitational) gradient tensor can be applied as the additional
internal parameters for the gravity gradient tensor, which have been widely used in the …

In recent years, there are research trends from constant to variable density and low-order to
high-order gravitational potential gradients in gravity field modeling. Under the research …

The differences between local and reference geopotential values are the fundamental
quantities of interest in the geodetic boundary value problem approach for connecting …

The paper describes a method of gravity data inversion, which is based on parallel
algorithms. The choice of the density model of the initial approximation and the set on which …

Objectives Taylor series expansion is often used in the downward continuation of potential
