现代小卫星及其关键技术

工程技术和科学、艺术一样，发展最终的目标将追求简化性和完善性。现代小卫星出现，说明航天技术正沿着这条规律向前发展。由于小卫星具有质量轻、体积小、成本低、性能高、研制周期短的显著优点，人们预测：小卫星发展将引起卫星应用和卫星技术方面一场重大变革。首先论述小卫星的概念和兴起的原因；其次讨论小卫星发展概况；最后研究小卫星关键技术。

MODERN SMALL SATELLITES AND ITS KEY TECHNOLOGY

In engineering, as in science and the arts, evolutionary processes ultimately lead to simplification and perfection. The rise of modern small satellites show that the space technology is developing forward in this way.Because of the remarkable advantages of the small satellites, such as light weight, small size, low cost, high performance and short development time, expect:the development of small satellites will bring about a great revolution to satellite application and satellite technology.In this paper, the concept and background of small satellites were expounded at first. Secondly the survey of their development were made. Finally. the key technology of small satellites were studied.
