低轨卫星通信遥感融合:架构、技术与试验

Communication and remote sensing integrated LEO satellites:architecture,technologies and experiment

低轨卫星系统是获取空间信息和破解宽带数字鸿沟的重要基础设施之一,通信与遥感融合是解决现有遥感和通信分治、卫星重置、应急业务响应不及时等问题的有效途径。概述了低轨通信和遥感卫星系统的现状,针对通信和遥感融合需求,提出了通信遥感融合方案及体系架构,阐述了基于该体系架构的硬件组成及融合试验方案,最后探讨了相关挑战和未来发展。

Low earth orbit(LEO)satellite system is one of the most important infrastructures to gather spatial infor-mation and break the broadband digital divide.The integration of communication and remote sensing is an effective way to solve the existing problems of system independence,satellite resource waste,and late response to emergency service requests.Firstly,the status of communication and remote sensing in LEO satellite systems were outlined,and then a communication and remote sensing integrated scheme and architecture were put forward to meet the integra-tion requirements.In addition,a hardware composition and corresponding experiment based on this architecture was introduced.Finally,the relevant challenges and future development were discused.
