用于行星可视化测绘的航天器群姿态控制

Attitude Control of Spacecraft Swarms for Visual Mapping of Planetary Bodies

Ravi Teja Nallapu, Jekan Thangavelautham

摘要:

小行星、彗星和行星卫星等行星体是高价值的科学目标,因为它们拥有关于太阳系形成和演化的重要信息。然而,由于它们的低重力,可变的大小和形状,围绕这些目标体的专用轨道航天器任务是困难的。因此,在飞越遭遇期间观测到许多行星体,因此,目标体的测绘范围有限。在这项工作中,我们建议使用的航天器群提供完整的表面地图的一个行星体在近距离接触飞越。随着低成本航天器技术的进步,可以通过使用多个微型航天器来实现这样的群体。群体任务的设计是一个复杂的多学科问题。首先,我们提出了群的集成设计工程与自动化(IDEAS)软件。在这项工作中,我们将介绍该软件的自动群设计器模块的开发,并将其应用于小行星433爱神星的全表面测绘。

英文摘要:

Planetary bodies such as asteroids, comets, and planetary moons are high-value science targets as they hold important information about the formation and evolution of our solar system. However, due to their low-gravity, variable sizes and shapes, dedicated orbiting spacecraft missions around these target bodies is difficult. Therefore, many planetary bodies are observed during flyby encounters, and consequently, the mapping coverage of the target body is limited. In this work, we propose the use of a spacecraft swarm to provide complete surface maps of a planetary body during a close encounter flyby. With the advancement of low-cost spacecraft technology, such a swarm can be realized by using multiple miniature spacecraft. The design of a swarm mission is a complex multi-disciplinary problem. To get started, we propose the Integrated Design Engineering & Automation of Swarms (IDEAS) software. In this work, we will introduce the development of the Automated Swarm Designer module of the software and apply it to total surface mapping of asteroid 433 Eros through flybys.
