永久性低轨道空间站有效运行的设计方案要考虑自主问题,这种设计方法与其它空间系统所用的设计方法绝然不同。空间站长期实际支持对空间部分所要求的自主程度,比以往“阿波罗”飞船和航天飞机这类载人计划更高。由于空间站上有乘员,因而与不载人的卫星相比,更应该强调系统的安全性和完善性,同时,应该注意发挥乘员有效参与空间部分工作后所能发挥的潜力。本文着重从制导、导航和控制功能角度,论述有关空问站自主的一些重大设计问题。
Designing solutions for the effective operation of a permanent low-orbit space station takes autonomy into consideration, a design approach that is quite different from that used in other space systems. The degree of autonomy required for long-term physical support by space stations for the space component is higher than in previous manned programs such as the Apollo spacecraft and space shuttle. Owing to the crew members on the space station, the security and sophistication of the system should be emphasized more than unmanned satellites. At the same time, attention should be paid to the potential that the crew can play in effectively engaging part of the space. This article focuses on the guidance, navigation and control functions from the point of view, discusses the air station independent some major design issues.
