摘　　要：天地一体化网络具备对遥感卫星实施全球实时测控和数传的能力,能够大幅改善卫星遥感系统效能严重受限于地面站资源的现状,极大地提高了卫星遥感系统的效能。基于上述思想,设计了一个具有基本接入和联通能力的通信星座,并对该星座的地面站接入能力和遥感卫星接入能力进行了初步分析。然后针对用户关心的点目标应急观测、区域目标应急覆盖和移动目标持续跟踪3类任务场景进行了仿真分析,量化说明天地一体化网络对卫星遥感系统效能的提升。Integrated satellite-terrestrial information network provides global real-time TT&C(Telemetry,Tracking and Control)and data transmission for remote sensing satellites,which greatly improves the efficiency of satellite remote sensing system by overcoming the serious limitation imposed by ground station resources.A concept of integrated satellite-terrestrial information network with basic capability of access and connectivity is designed,and its capability of ground station accessing and remote sensing satellite accessing is analyzed.Then,three kinds of scenarios,including point target emergency observation,area target emergency coverage and moving target continuous tracking,are simulated and analyzed,and an quantitive description is provided on the improvement of remote sensing system efficiency by the integrated satellite-terrestrial information network.
