基于SpaceVPX架构的星上高速载荷数据实时处理平台设计

Spaceborne High-speed Payload Data Real-time Processing Platform Design Based on SpaceVPX Architecture

针对星上载荷数据速率提高,现有处理平台无法支持高速载荷数据实时处理、快速应用的问题,文章通过对卫星在轨处理需求的分析,介绍了基于SpaceVPX标准的星上载荷数据高速数据处理平台的设计方案,重点阐述了针对宇航应用的特殊需求所设计的自主容错和故障隔离方案,并在某光学载荷在轨图像处理系统中进行了应用验证,结果表明:采用该方法设计,系统处理速度高,可扩展、可重构性强,软件和硬件之间的关联度较弱,可为星上高速载荷处理系统设计提供参考。

Due to the improvement of on-board payload data rates,the processing platform should support high-speed payload data real-time processing and rapid application any more.In this paper,by analyzing on-orbit processing requirements,a novel design of spaceborne high-speed data processing platform based on SpaceVPX satndard is provided,and it carries out the corresponding designs including self-fault tolerant and fault isolation in order to meet its special space requirements.The design method has been verified in the image processing system of one certain optical payload in orbit.The result shows the advantages of this design,including high-speed processing performance,expandable,reconfigurable,weak correlation between software and hardware.It can provide a reference for on-board high-speed payload processing system design.
