摘要
软件定义技术的高速发展有望引发航天产业新一轮的技术革新。文章分析了未来航天器发展的总体趋势和软件定义航天器的发展现状;针对未来航天器灵活、自主和快速的发展需求,提出了一种软件定义航天器系统架构,其具有设计分层化、接口规范化、硬件通用化、功能软件化和资源虚拟化等技术特征。相比以往的航天器系统架构,它将软件定义扩展至整个航天器,并充分考虑了航天器的固有特征。文章分析了该架构对未来航天器发展需求的满足情况,梳理了开放架构与规范、器载操作系统、器载超算平台和安全机制4项关键技术,并提出进一步细化系统架构、形成标准规范的发展建议。
The rapid development of software definition technology is expected to lead a new round of technological innovation in aerospace industry.In this paper,the spacecraft development trends in the future and the status of software-defined spacecraft are analyzed.An architecture for software-defined spacecraft is proposed for the needs of future spacecraft including flexibility,autonomy and rapidity.The technical features of the architecture are summarized,including hierarchical design,standard interface,generalized hardware,function based on software,and resource virtualization.Compared with the previous spacecraft system architecture,the proposed architecture extends software definition technologies to the entire spacecraft and takes full account of the inherent characteristics of the spacecraft.In this paper,the satisfaction of the architecture to the future spacecraft development requirements is analyzed.The key technologies are given including open architecture and specification,onboard operating system,onboard super computing platform and security mechanism.Finally,some suggestions are proposed including refining the system architecture and forming standards and specifications.
