面向卫星通导遥算融合的关键技术分析
Analysis of Key Technologies for Satellites Oriented to the Fusion of Communication,Navigation,Remote Sensing and Computing
摘要
Abstract
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.关键词
