天地一体通遥融合架构及其应用设想

Integrated Architecture and Application Assumption of Earth-Space Communication and Remote Sensing Combination

遥感系统是天基对地观测的重要手段,由于在“采集-处理-分发”等环节中存在测控指令、数据传输、数据处理及产品分发不及时等问题,难以有效实现全天时、全天候、全球覆盖的实时智能遥感应用服务,低轨星座的通信和遥感的融合是解决现有天基系统中通遥分治、服务响应滞后等问题的有效途径。概述国内外通遥融合现状,设想天地一体通遥融合总体架构、发展阶段及其服务模式,提出通遥融合架构下的关键技术,最后以典型应用场景进行通遥融合应用流程的探索。

Remote sensing systems are important means of space-based Earth observation,due to issues such as delayed measurement and control commands,data transmission,data processing,and product distribution in the"collection-processing-distribution"process,it is difficult to effectively achieve real-time intelligent remote sensing application services that cover all day,all weather,and the world.The combination of low earth orbit communication and remote sensing satellite constellations is an effective way to solve service delay and separate control problems in existing systems.It summarized the current situation of communication and remote sensing integration over the world,and then imagined the architecture,development stages,and service modes of the integration of communication and remote sensing.Finally,key technologies under the communication and remote sensing integration architecture were proposed,and the application process of communication and remote sensing integration used typical application scenarios were explored.
