在轨航天器轨道规避体系研究

Exploring Further On-orbit Spacecraft Collision Avoidance Framework(OSCAF)

针对在轨航天器主动防护的问题,文章综合考虑了未来航天器规避原则和规避过程中可能出现的因素,提出了在轨航天器轨道规避体系的构造思路。根据规避对象为空间碎片和航天器时的情况,建立了相应的规避基础框架;并利用事例对其中一个基础框架进行了分析和验证。分析结果表明,在轨航天器规避框架的研究对于降低航天器潜在威胁、增强航天器在轨运行安全具有积极的作用。

Aim. To our knowledge, Ref. 5 authored by K. R. Keagan is the only paper in the open literature dealing with many aspects of the topic mentioned in the title. Starting from Ref. 5, our exploration goes further. Table 1 in subsection 1.2 of the full paper presents as usual the three stageε of OSCAF design but Lheir contents include the resuits of our exploration. Fig. 1 in subsection 2.1 presents the block diagram of OSCAF design for spacecraft versus debris and Fig. 2 also in subsection 2.1 presents that for spacecraft versus spacecraft. Section 3 presents an example concerning spacecraft versus spacecraft. Table 2 in section 3 gives the information about the conditions under which two spacecraft collide. Possessing such information can ensure the avoidance of the collision of two spacecraft.
