低轨卫星可提供更精准、更高效的多源数据融合信息服务。深入分析低轨卫星在轨特性对星座网络的影响,设计融合了卫星的再生处理、透明转发、子带转发等多服务场景的载荷配置方案。针对星座网络拓扑变化对服务性能的影响,以及多类用户不同应用模式需求,从载荷配置、交换架构、控制机制、星间高速通信4个关键维度,开展低轨星座载荷系统设计与星地一体化路由交换技术研究,并进行路由交换典型性能测试验证。目前,该技术已成功应用于某低轨卫星互联网试验星。
Low Earth Orbit (LEO) satellites are capable of delivering more precise and efficient multi-source data fusion information services. This paper delves deep into the impact exerted by the on-orbit characteristics of low-orbit satellites on the constellation network. Based on this analysis
a payload configuration scheme is devised
which seamlessly integrates multiple service scenarios
including satellite regenerative processing
transparent forwarding
and sub-band forwarding. In view of the negative effects of constellation network topology changes on service performance and the diverse application mode demands of various user groups
this study conducts in-depth research on the design of the low-orbit constellation payload system and satellite-ground integrated routing and switching technology. The research is carried out from four crucial aspects: payload configuration
switching architecture
control mechanism
and inter-satellite high-speed communication. Moreover
the typical performance of routing and switching is validated through rigorous tests. Currently
this technology has been successfully implemented in a specific low-orbit satellite Internet experimental satellite.
