摘要

低地球轨道卫星网络可以提供全球宽带接入服务，因此是对目前地面移动通信系统的补充。低轨道卫星平台资源有限，地面业务分布不均，给卫星地面接入方案的设计带来诸多挑战。跳波束技术通过时间切片技术满足了用户的非均匀动态业务需求，提高了卫星资源利用率和服务能力。然而，BH技术在近地轨道卫星上的应用面临着诸多挑战。本文从系统和技术两个方面进行分析和思考，对其研究工作进行梳理和分析。最后，给出了BH系统的发展趋势，为BH技术在近地轨道卫星上的应用和发展提供了思路。

Beam Hopping for LEO Satellite:Challenges and Opportunities

Low earth orbit (LEO) satellite networks can provide global broadband access services and thus are complementary to current terrestrial mobile communication systems. The limited resources of LEO satellite platform and the uneven distribution of ground services bring many challenges to the design of satellite ground access scheme. The beam hopping (BH) technology meets the non-uniform and dynamic service requirements of users through time slicing technology, and enhances the resource utilization and service capability of satellites. However, the application of BH technology in LEO satellites is facing many challenges. This paper analyzes and considers from the system and technical aspects, combs and analyzes its research work. Finally, the development trend of BH system is given, which provides an idea for the application and development of BH technology for LEO satellites.
