摘要:

卫星通信和地面移动通信具有较强的互补性,卫星互联网是当前产业发展的热点,也是未来6G网络的重要组成部分。全球覆盖需要星间组网,但星间通信带宽需求与自由空间信道带来的不稳定性对空间承载网提出了新的挑战。对星间通信及其传输链路进行对比分析,提出了基于星间激光的光传送网络(OTN)承载方案,以充分发挥地面光通信的成熟产业链优势和规模经济优势,构建经济性、兼容性、扩展性强的星地一体化网络。最后展望了星间激光通信的技术演进方向,并提出了我国产业发展建议。

Abstract:

Satellite communication and terrestrial mobile communication have strong complemented co-benefits.Satellite Internet is the hot spot supporting current industrial development and an important part of the future 6G network.Global coverage requires interstellar networking, but inter-satellite communication bandwidth requirements and the instability brought by the free space channel pose new challenges to the space bearer network.Inter-satellite communication technologies and link interface technologies were compared and analyzed.An optical transport network (OTN) carrier network solution based on inter-satellite laser was proposed, which could fully leverage the advantages of the maturities and the economies of the scaled ground optical communication.It constructs a satellite-terrestrial integrated network with strong cost-efectivity, compatibility, and scalability.Finally, the technological directions and evolutions of the inter-satellite laser communication were discussed, and suggestions for industrial development in China were proposed.

Key words: satellite Internet, inter-satellite laser communication, OTN, satellite-terrestrial integrated network, 6G
