摘要: 通信(广播)卫星是典型的有长寿命要求的卫星。在广泛调查国内外通信卫星工程资料的基础上,考察了它们的轨道性能与寿命情况,并分析了影响卫星寿命和可靠性的因素,空间环境是影响卫星性能和寿命的一个重要因素。对为了避免和减少环境效应影响的工程方法进行了探究。结合工程实际问题研究了长寿命卫星的设计策略,并对需进一步研究的课题作了探索。

关键词: 通信卫星, 寿命, 可靠性, 影响因素, 研究

Abstract: Study of communication satellite(CS)s reliability not only could help to solve its engineering problems but also would play an important role for long-life spacecraft engineering.On the basis of wide researching the information on communication satellites home and abroad,the works on surveying their performances on orbit and analysing the elements which influence their life and reliability have been done.Space environment is the important one in these elements. The study of methods for reducing or avoiding its effects,that is "spacecraft immunity engineering for environment",has also been done.Other design strategies for long-life spacecraft have been studied. The design experience has been synthesized and the subjects which need further study have been searched.
