We optimize a six degrees of freedom hovering policy using reinforcement meta-learning.
The policy maps flash LIDAR measurements directly to on/off spacecraft body-frame thrust …

This paper proposes a new nonlinear guidance algorithm applicable for asteroid both
hovering and landing. With the new guidance, a spacecraft achieves its target position and …

This paper addresses the control of spacecraft hovering about uniformly rotating asteroids
using only position measurements. The highly uncertain dynamical environments and the …

Based on the inherent coupling of system states, backstepping controllers are designed for
underactuated spacecraft hovering without either the radial or in-track thrust and in the …

小行星探测是当前深空探测的主要方向之一, 具有重要的科学意义. 绝大多数小行星引力场极不
规则, 探测器在小行星附近运动形态复杂多样. 由于同时受到中心引力, 快速自旋的不规则形状摄 …

The design of an attitude control system for an asteroid-orbiting satellite via immersion and
invariance is the subject of this paper. It is assumed that the asteroid is rotating with a …

SCIENTIFIC exploration of small bodies (asteroids and comets) contributes greatly to
understanding the origin and evolution of the solar system. In the past, several exploratory …

An adaptive control law is proposed in this paper for body-fixed hovering over an asteroid
with an unknown gravity field and an unknown rotation rate. The unknown parameters and …

Frozen orbits are ideal options for global mapping and observation. In this paper, a design
and maintenance method of frozen orbit is presented and applied to the small body …
