摘要:
随着 6G 架构的逐渐清晰与天空地海一体化需求的明确,非静止轨道卫星星座的发展进入了空前繁荣的阶段,美国 STARLINK、Kuiper、英国 OneWeb、中国卫星互联网星座等系统
处于建设与部署的关键阶段。 其中,多层星座网络的设计是解决全球无缝覆盖与随需接入的重要研究对象。 然而,受限于卫星通信系统建设成本高、系统复杂、正式系统运行受国家管控等,真实系统难以直接应用于高等院校的实验教学工作。 目前卫星通信相关课内实验及综合实验主要以机房参观、实验箱分组实验等方式进行,既缺乏直观的系统认识,且参与度较低。 针对上述需求,该文设计了一套基于“ 轨道建模+系统分析+动态显示" 的仿真系统,并利用快照仿真的思想实现了非静止轨道卫星星座的高动态性分析过程。 实验结果表明,该系统能够较好地完成大规模多层星座网络的覆盖分析、同频干扰分析等功能,可支撑卫星通信、无线通信、通信综合实验等课程的实践需求。
Abstract:
With the gradual clarity of 6G architecture and the clear demand for the integration of space and terrestrial,the development ofnon-geostationary orbit satellite constellation has entered a stage of unprecedented prosperity. Some typical system,such as the UnitedStates' STARLINK,Kuiper,the British OneWeb,Chinese Satellite Internet Constellation stay at a critical stage of construction and deployment. Among them,the design of the multi-layer constellation network is an important research object to solve the global seamless coverage and on-demand access. However,due to the high cost of satellite communication system construction,the complexity of thesystem and the government control of the real system, it is hard to directly apply the real satellite communication system to theexperimental teaching of colleges and universities. At present, the classroom experiments?
and comprehensive experiments related tosatellite communication are mainly carried out by visiting the computer room and grouping experiments in experimental boxes,which lackintuitive system understanding and low participation. Aiming at the above requirements,we design a simulation system based on " orbitmodeling+ system analysis + dynamic display " , and realize the highly dynamic analysis process of non - geostationary orbit satelliteconstellation by using the idea of snapshot simulation. The experimental results show that the system can well complete the coverageanalysis of large-scale multi-layer constellation network,the co-channel interference analysis and other functions,which can support thepractical needs of satellite communication,wireless communication,communication comprehensive experiment and other courses.
