空天技术深入发展后,用户对空天系统的要求将是融合通信、遥感、导航卫星的天基信息服务系统,以向用户提供高速数据传输、直达用户的实时遥感服务、精确到厘米以内的高精度定位导航、分布式协同计算资源等服务能力,从而应用于丰富的服务场景.现有的通信、导航、遥感卫星存在软件协议和物理设施上的屏障,不能融合应用,远远不能满足天基信息服务系统的建设要求,因此,有必要研究通信、导航、遥感、计算在卫星上的融合.融合关键点是硬件和软件资源的可调度、可共享,以及高效能、高稳定性的载荷器件.基于此,深入分析面向卫星通导遥算融合的关键技术,并分析通导遥算融合的典型应用服务方式,最后通过仿真实验可验证融合后的效能提升.
Analysis of Key Technologies for Satellites Oriented to the Fusion of Communication,Navigation,Remote Sensing and Computing
After the in-depth development of space technology,the user's requirement for space system will be anintegrated space-based information service system that integrates communication,remote sensing and navigation satellites in order to provide the user with ser-vice capabilities such as high-speed data transmission,real-time remote sensing services directly to the user,high-precision positioning and navigation accurate within centimetres,and distributed collaborative computational resources,so as to be applied to a rich variety of service scenarios.However,existing communication,navigation and remote sensing satellites have barriers in terms of software pro-tocols and physical facilities,which prevent them from integrating applications and are far from meeting the requirements for the con-struction of space-based information service systems.Therefore,it is necessary to study the fusion of communication,navigation,re-mote sensing and computation on satellites.The key points of fusion are schedulable and shareable hardware and software resources,and high-efficiency high-stability payload devices.Based on thes,the paper introduced and analyzed the key technology oriented to the fusion,and analyzed the typical application service mode of communication,navigation,remote sensing and computation fusion.Simu-lation experiments verified the performance enhancement after fusion.
