摘要
针对传统小卫星电子系统功能冗余、快速开发能力不足及成本难以降低的问题,提出了一种基于功能分区的小卫星电子系统架构。硬件层面按功能聚类核心分区,明确分工,统一算力;软件层面采用面向服务架构实现整星软件的统一开发,提升了快速开发能力。系统兼具高集成度、强算力与柔性架构,在批量化生产和星座协同方面优势显著。通过架构优化实现了轻量化与低功耗的突破,质量显著减小,功耗大幅优化,大幅降低了发射成本与在轨能耗,为卫星长寿命运行及大规模星座部署提供了关键支撑,契合卫星商业化发展趋势,为小卫星综合电子系统的创新发展提供了有益探索。
Aiming at the problems of redundant functions,insufficient rapid development capability,and difficulty in cost reduction of traditional small satellite avionics systems,a small satellite avionics system architecture based on functional partitioning was proposed.At the hardware level,core partitions were clustered by function with clear division of labor and unified computing power.At the software level,a service-oriented architecture was adopted to realize the unified development of the entire satellite’s software and improve rapid development capability.The system features high integration,strong computing power,and a flexible architecture,demonstrating significant advantages in mass production and constellation collaboration.Through architectural optimization,it achieves breakthroughs in lightweight design and low power consumption were achieved.The launch cost and onorbit energy consumption are also reduced significantly,providing key support for the long-life operation of satellites and large-scale constellation deployment.Aligning with the commercialization trend of satellites,the architecture offers valuable exploration for the innovative development of small satellite integrated avionics systems.
