摘要：
To solve the problem that satellite product often has short life span and improve the life span of resource business satellite, many specific methods to improve the reliability of satellite product have been proposed. Taking satellite high-speed data multiplexer as an example, this paper shows the hardware structure and software flow diagram of high-speed data multiplexer. Using the methods of redundant design, derating design, thermal design, anti-radiation design and ESD protection which are the ideas of reliability design, some specific measures of reliability design are provided. By means of improving the reliability of the power module, differential data receiving module, SRAM cache module, differential data sending module of the Satellite high-speed data multiplexer, the reliability prediction result increases from 0.97326 to 0.98526. Through reliability design of hardware and software, the reliability prediction result of the satellite high-speed data multiplexer increases, this method of improving reliability can also be applied in other system of satellite product.
