手机直连卫星通信系统备受关注,分析了3种技术路线,指出5G NTN将是主流技术。阐述手机直连卫星通信系统在发展过程中面临的挑战与应对方案,指出星载相控阵天线是提升网络性能的核心要素。进一步深入分析星载相控阵天线的现状、趋势与挑战,权衡单星性能与星座规模、初期研发成本与长期运维成本、技术风险与系统可靠性,通过系统级多目标优化,提出发展5G NTN星载相控阵天线的建议与权衡策略,为我国建设与5G NTN手机直连卫星系统相关的工程和实践提供参考,并为6G星地融合全球竞争奠定基础。
The direct-to-mobilephone satellite system has attracted much attention
covering three technical routes. It was pointed out that 5G NTN would be the mainstream technology for the direct-to-mobilephone satellite system. The challenges confronted and corresponding solutions adopted by the direct-to-mobilephone satellite system during its development process were expounded. It was pointed out that the satellite-borne phased array antenna was the core and key element for enhancing network performance. A further in-depth analysis was conducted on the current situation
trends
and challenges of the satellite-borne phased array antenna. Trade-offs were made between single-satellite performance and constellation scale
initial research and development costs and long-term operation and maintenance costs
as well as technical risks and system reliability. Through system-level multi-objective optimization
suggestions and trade-off strategies for the development of the satellite-borne phased array antenna were proposed
providing references for 5G NTN engineering and practices in China.
