摘　　要：随着组网技术和传输技术的发展,提高信息的在轨处理和多源信息融合能力是提升天地一体化信息网络服务能力急需解决的重点问题。针对目前卫星具有的处理和存储能力,文中研究天基信息业务流程及处理模式,可有效简化传统卫星的通信过程,降低星地传输链路带宽损耗。文中设计一种分布式、网络化天基信息在轨处理系统,该处理系统基于CPU、DSP、GPU等不同的异构资源搭建,通过虚拟化技术将不同轨道、不同类型的卫星资源逻辑上形成一个大的资源池,实现处理系统的灵活扩展、互为备份、协同服务等。With the development of networking technology and transmission technology,it is urgent to improve the in-orbit processing of information and the ability of multi-source information fusion.In view of the current satellite processing and storage capacity,this paper studies the business process and processing mode of space-based information,which can effectively simplify the communication process of traditional satellites and reduce the bandwidth loss of satellite-ground transmission link.This paper designs a distributed,networked space-based information on-orbit processing system,which is built based on heterogeneous resources such as CPU,DSP,GPU,etc.Through virtualization technology,different orbits and different types of satellite resources are logically formed into a large resource pool to realize flexible expansion of processing system,mutual backup and collaborative service.
