摘要

卫星互联网具备全球广域无缝覆盖能力，是未来陆海空天一体化网络的重要组成部分。首先，讨论了卫星互联网体系架构，包括系统一般组成、组网方式、工作过程等，研究了卫星互联网场景下的宽带和窄带业务模型建模方法，以提取业务的空时分布不均特征；然后，分析了频谱共享中的星间同频干扰问题，初步分析表明未来非地球同步轨道（NGSO）星座间会存在较严重的同频干扰，探讨了低轨卫星波束成形设计和高轨卫星跳波束设计方案，通过高效挖掘空间域资源，可显著提升系统容量；最后，对卫星互联网领域的几个技术发展方向进行了展望。

Abstract

Satellite Internet has the ability of global seamless coverage

which will be an important part of the future land-sea-air-space integrated network.Firstly

the architecture of satellite Internet was discussed

which included the general composition of the system

networking mode

working process

etc.Secondly

the methods of modeling broadband and narrowband traffic were proposed to extract the uneven space-time distribution characteristics of traffic for satellite Internet.Then

the co-frequency interference of spectrum-sharing was analyzed

showing that there would be more serious co-frequency interference among different non-geostationary satellite orbit (NGSO) constellations in the future.Next

the schemes of both beamforming design for low earth orbit satellite and beam-hopping design for high orbit satellite were explored

which could significantly improve the system capacity through efficient mining of space-domain resources.Finally

the development prospect of several technologies of satellite Internet were given.
