This paper focuses on estimating a new high-resolution Earth's gravity field model named
SGG-UGM-2 from satellite gravimetry, satellite altimetry, and Earth Gravitational Model 2008 …

Forward gravity modeling in the spectral domain traditionally relies on spherical
approximation. However, this level of approximation is insufficient for some present day high …

During the last few years, the determination of high-resolution global gravity field has gained
momentum due to high-accuracy satellite-derived observations and development of forward …

The Earth's shape is much closer to an ellipsoid than a sphere. The commonly used
spherical approximation in mass change inversion is expected to cause bias by the …

A recursive method is developed to compute the ratios of the oblate spheroidal harmonics of
the second kind and their first-, second-, and third-order derivatives. The recurrence …

Gravity forward modeling provides important high-resolution information for the development
of global gravity models, and can also be applied in many studies, eg, topographic/isostatic …

A high-resolution global magnetic gradient tensor (MGT) model is an essential tool for aided
navigation. However, the high-order expansion using the traditional spherical harmonic (SH) …

We investigate the orthogonality of the potential distributions that are the basis solutions of
Laplace's equation appropriate to 3-D ellipsoidal (including spheroidal) coordinate systems …

A complete orthogonal system for the monogenic L 2-space consisting of solid oblate
spheroidal monogenics in 3 is constructed by means of harmonic functions. The lack of …

椭球谐函数级数展开是地球重力场椭球谐建模的基础. 然而, 处理椭球谐函数级数的主要困难
在于计算第二类勒让德函数. 而Jekeli 的重规格化方法简化了这一计算过程. 本文在Jekeli …
