摘要
传统卫星平台计算处理能力有限,主要采用星上存储、过境回传、地面处理、分发应用的模式,天基信息服务响应速度慢、服务周期长。为提高天基信息系统服务能力,必须提高天基平台计算处理能力,实现信息在轨实时处理、快速分发、快速应用。本文提出了一种新型的天基网络化计算平台体系架构,设计了硬件架构、软件架构以及容错架构,结合典型演示案例,证明了该体系结构的可行性。
Restricted by the ability of on-board information processing,the space information is usually stored in the space-based information systems,transmitted to the ground systems,and processed by the ground systems,which restrict the service ability of the space-based information system.So improving the on-board information processing capacity is important to the space-based information system and helpful to promote the military and civil network information system.This paper proposed a novel space-based information system based on an open architecture,which could improve the ability of on-board information processing.The hardware architecture,the software architecture and the fault tolerance architecture have been discussed in detail.Finally,the practicability of the novel space-based information system by the case study.The research in this paper is helpful to promote the network information system.
