采用商业元器件降低航天器成本研究

Using COTS to reduce the cost of spacecraft

采用商业元器件被认为是降低航天器成本的最直接途径,但是采用商业元器件必须面对一系列的技术和非技术问题。分析了采用商业元器件的原因,指出采用商业元器件降低航天器成本的可行性,然后对必须面对的问题进行了分类概括,并针对这些问题初步给出了对策。

In recent years,the adoption of commercial-of-the-shelf（COTS） has been believed as a direct way to reduce the cost of spacecraft,but there are some potential pitfalls either technical or non-technical for the use of COTS. This paper describes the reasons of the use of COTS,points out the possibility of the successful use of COTS,and discusses the problems that have to be faced. At the end of this paper,some countermeasures are presented for the successful use of COTS.
