Weak stability regions serve as superior locations for interferomertric scientific investigations. These regions are often selected to minimize environmental disturbances and maximize observation efficiency. Designs of formations in these regions are becoming ever more challenging as more complex missions are envisioned. The development of algorithms to enable the capability for formation design must be further enabled to incorporate better understanding of weak stability boundary solution space. This development will improve the efficiency and expand the capabilities of current approaches. The Goddard Space Flight Center (GSFC) is currently supporting multiple formation missions in weak stability boundary regions. This end-to-end support consists of mission operations, trajectory design, and control. It also includes both algorithm and software development. The Constellation-X, Maxim, and Stellar Imager missions are examples of the use of improved numeric methods to attain constrained formation geometries and control their dynamical evolution. This paper presents a survey of formation missions in the weak stability boundary regions and a brief description of formation design using numerical and dynamical techniques.
弱稳定性区域是干涉科学研究的理想场所。这些区域通常被选中以尽量减少环境干扰并最大化观测效率。随着设想的任务越来越复杂，这些区域的编队设计变得越来越具有挑战性。必须进一步开发算法以实现编队设计能力，从而更好地理解弱稳定性边界解空间。这一发展将提高当前方法的效率并扩展其能力。戈达德太空飞行中心（GSFC）目前正在支持多个在弱稳定性边界区域的编队任务。这种端到端的支持包括任务操作、轨道设计和控制。它还包括算法和软件开发。星座-X、马克西姆和恒星成像仪任务就是利用改进的数值方法来实现受限编队几何形状并控制其动态演化的例子。本文介绍了对弱稳定性边界区域编队任务的综述以及使用数值和动力学技术进行编队设计的简要描述。
