摘要/Abstract

摘要：

航天器的测控、数据传输分为天基和地基两种方式，其中天基的测控、数据传输因具有全球覆盖、随遇接入、实时信息回传等优势，具有很广泛的应用前景，同时对其多航天器的动态带宽分配提出了一定要求。在研究中高轨测控、数据传输星座网络架构和多址接入协议的基础上，提出面向数据传输任务的星上多波束、多航天器用户、多任务优先级的动态带宽分配算法，能很好地应用于中高轨星座按需、实时对多个用户的数据传输请求进行资源分配，并可作为天基测控、数据传输接入网络的基础模型。

关键词: 中高轨星座, 测控数据传输, 多址接入, 动态带宽分配

Abstract:

The TT＆amp;C and data transmission of spacecraft are divided into two methods: space-based and ground-based.Among them, space-based method has the advantages of global coverage, access at any time, and real-time information return, and have a wide range of application prospects.But it also puts forward certain requirements for the dynamic bandwidth allocation of its multi-spacecraft.Based on the studied of medium-orbit TT＆amp;C, data transmission constellation network architecture and multiple access protocols, a dynamic bandwidth allocation algorithm for on-doard multi-beam, multi-spacecraft users, and multi-task priorities for data transmission tasks was proposed.It was very suitable for the on-demand and real-time resource allocation of data transmission requests of multiple spacecraft in the mid-orbit constellation, and could be used as a multiple access protocol model for space-based measurement and control and data transmission access networks.

Key words: medium-high orbit constellation, TT＆C and data transmission, multiple access, dynamic bandwidth allocation
