Prior to the Near Earth Asteroid Rendezvous (NEAR) mission, little was known about Eros
except for its orbit, spin rate, and pole orientation, which could be determined from ground …

The objective of the Dawn gravity investigation is to use high precision X-band Doppler
tracking and landmark tracking from optical images to measure the gravity fields of Vesta …

The Vesta gravity field and related physical parameters have been precisely measured
using 10-months of radiometric Doppler and range data and optical landmark tracking from …

High-fidelity representations of the gravity field underlie all applications in astrodynamics.
Traditionally these gravity models are constructed analytically through a potential function …

In this paper, the basic classification of asteroids and the history and current situation of
asteroid exploration are introduced. Furthermore, some recent research progress on the …

The characteristics of the interior gravity field are derived, summarized, and evaluated near
the surface of an asteroid for the purpose of small body proximity operations. In order to …

Four widely used algorithms for the computation of the Earth's gravitational potential and its
first-, second-and third-order gradients are examined: the traditional increasing degree …

As part of the NEAR Radio Science investigation, a global solution that includes both
spherical and ellipsoidal harmonic gravity fields of Eros, Eros pole and rotation rate, Eros …

OVER the past decade, there has been a growing interest in exploring small bodies (ie,
asteroids, comets, and planetary satellites). To name a few, missions such as NEAR (1996) …
