针对全球气候变化背景下我国极端灾害损失加剧与现有卫星系统在应急响应中存在的三重短板,即卫星数据回传窗口期受限、通导遥分立部署导致端到端时延增加、单一卫星失效引发高危区域响应延误,提出“中高轨通信导航中继层+异构低轨感知层”的通导遥一体化星座架构。中高轨卫星通过Ka频段星间链路实现低轨卫星跨境数据的实时回传,并基于星基增强系统广域差分改正数将低轨定位精度提升至厘米级;低轨层针对中国城市群与林火高危区,创新设计了混合倾角异构、晨昏轨道群组化和功能分层解耦3种载荷异构(可见光/红外/合成孔径雷达)的轨道协同方案,并集成小型化导航载荷实现快速感知与精准定位的一体化。仿真实验结果表明,晨昏轨道群组化方案在覆盖均衡性与多载荷协同性上的表现均优于混合倾角异构和功能分层解耦方案,该星座设计方案可以为城市灾害防御提供关键技术支撑。
Addressing the exacerbated extreme disaster losses in China under the context of global climate change and the triple gaps of existing satellite systems in emergency response—limited satellite data return windows
increased end-to-end latency due to segregated deployment of communication
navigation and remote sensing
and single-satellite failures causing response delays in high-risk areas
a constellation architecture integrating communication
navigation and remote sensing is proposed
featuring a "medium-high orbit communication and navigation relay layer + heterogeneous low orbit sensing layer". The medium-high orbit satellites enable real-time cross-border data downlinking for low orbit satellites via Ka-band inter-satellite links and enhance low orbit satellites positioning accuracy to the centimeter level using SBAS wide-area differential corrections. For China’s urban agglomerations and high-risk forest fire zones
the low orbit layer innovatively designs three types of orbit synergy schemes featuring payload heterogeneity (visible light/infrared/SAR): mixed-inclination heterogeneous architectures
dawn-dusk orbit clusters
and functionally layered disaggregation. It integrates miniaturized navigation payloads to achieve integrated rapid sensing and precise positioning. Simulation results show that the dawn-dusk orbit cluster scheme outperforms the mixed-inclination heterogeneous and functionally layered disaggregation schemes in terms of coverage uniformity and multi-payload synergy. This constellation design can provide crucial technical support for urban disaster prevention.
