国外航天器电子系统的几个重要发展趋势

首先,界定了所讨论的航天器电子系统的范畴,即限于航天器平台或公共服务模块部分的电子设备。然后,从分布式模块化结构电子系统发展、工业标准体系的应用、空间电子单机与元器件先进制造技术影响和数字化设备应用等方面,综述了国外航天器电子系统技术十余年的发展成果和趋势,其中重视系统体系结构研究、工业标准向空间技术领域推广等经验值得借鉴。

Some Trends in Development of Foreign Spacecraft Avionics

The scope of spacecraft avionics discussed is defined as the avionics used in the platform or the service module of the spacecraft.The development trends of distributed modular avionics,standardization strategies,influence of advanced manufacture of units and elements and digital unit application in recent 10 years are summarized in this paper.The practices of the avionics architecture study,the industry standardization application in spacecraft and so on are valuable to avionics design.
