低轨航天器间的电位差异是航天器交汇对接面临的一个重大安全问题,分析了低轨航天器在电离层等离子体中的充电机制,并给出了等效物理电路模型。在此基础上分析了国际太空站的主动电位控制原理和方法,并针对航天器交汇对接中的电位控制问题给出了2种新的解决方案。最后,提出了航天器交汇对接中的电位监测方案,即由朗缪尔探针和表面电位探测器组成航天器电位监测包。
The potential difference between LEO spacecraft is a major safety issue facing the intersection of spacecraft and docking. The charging mechanism of LEO spacecraft in ionospheric plasma is analyzed and an equivalent physical circuit model is given. On this basis, the principles and methods of active potential control of the International Space Station are analyzed. Two new solutions to the problem of potential control in spacecraft docking and docking are given. Finally, the potential monitoring scheme of spacecraft docking and docking is proposed, that is, the spacecraft potential monitoring package consists of Langmuir probe and surface potential detector.
