手机直连卫星技术的快速发展是卫星载荷技术突破、手机终端技术创新、体制标准制定并验证等多种因素叠加的结果,通过对手机直连卫星发展现状的介绍,总结了手机直连卫星的2条技术路线和3种实现方式。面对星地频率共用、星载天线、星载基站等技术瓶颈,结合实际系统和应用场景给出了重点研究内容。探讨了作为5G通信重要组成部分和6G通信基础支撑的手机直连卫星技术未来的发展方向。
The technology of direct-to-handset satellite is developing rapidly
which is the result of many factors such as the breakthrough of payload technology
the innovation in mobile phone technology
and the standards verification. Through the introduction of direct-to-handset satellite
two technical routes and three realization methods of direct-to-handset satellite were summarized. According to the technical problems of satellite-ground frequency sharing
space-borne antenna and space-borne base station
the key research contents were given based on the actual system and application scenarios. As the component of 5G communication and the basic of 6G communication
the future development of direct-to-handset satellite were discussed.
