Asteroids' and comets' geodesy is a challenging yet important task for planetary science and
spacecraft operations, such as ESA's Hera mission tasked to look at the aftermath of the …

A gravitational field of an ore-bearing asteroid, which usually has an irregular shape and
heterogeneous density, is a prerequisite for asteroid exploration (eg, space mining) …

摘要近年来小行星探测已成为各航天大国的热点, 小行星引力场对研究其内部结构, 组成成分,
早期演化和探测器轨道设计, 着陆等方面有着极其重要的作用. 随着小行星探测数据的不断更新 …

We present a novel approach based on artificial neural networks, so-called geodesyNets,
and present compelling evidence of their ability to serve as accurate geodetic models of …

In order to obtain the gravitational field of a general finite body inside its Brillouin sphere, we
developed a new method to compute the field accurately. First, the body is assumed to …

We propose a new modified Parker's method for efficient gravitational forward modeling and
inversion using general polyhedral models. We have made several important modifications …

The orbital dynamics in the gravitational environment of irregular asteroids is an important
issue for space missions and a quite complex problem. In this paper we propose a …

This paper presents an improved algorithm for the 2D and 3D Fourier forward modeling of
gravity fields caused by polyhedral bodies with constant and exponential density …

Recent numerical studies on external gravity field modelling show that external spherical
harmonic series may diverge near or on planetary surfaces. This paper investigates an …

A novel, explicit, and efficient forward modelling of the spheroidal harmonic spectra of
external planetary gravitational fields is developed in this article. We introduce the oblate …
