摘　　要：针对中继卫星系统的技术发展及数据传输应用需求,分析了基于代理的数据传输模式存在的问题以及基于数据池(以下简称为池)的数据传输模式及优势,对我国未来中继卫星系统的地面数据传输体系进行了初步设计,包括基于池的数据传输体系架构、基于池的数据传输系统组成、基于池的多任务调度的运行方式,该体系可有效提高数据传输吞吐量、可靠性、实时性、灵活性,并针对基于池的地面数据传输体系的特性,提出体系建立时需要重点考虑通用数据传输设备硬件架构、标准化模块化、基于池的动态调度等技术问题。为下一代中继卫星地面传输分发发展提出了一种新思路。In view of the technical development and the demand of the data transmission application of data relay satellite system,the existing problems of agent-based data transmission mode,and the pool-based data transmission mode and its advantage are analyzed.The preliminary design of ground data transmission system of future data relay satellite system is presented including pool-based data transmission system and its composition,and operational mode of pool-based multi-mission scheduling.This system can improve the throughput,reliability,real-time,and flexibility of data transmission effectively.Based on features of pool-based ground data transmission architecture,technical problems are put forward to be considered in the process of establishing the system,such as the hardware architecture of common data transmission equipment,standardization and modularization,pool-based dynamic scheduling and so on.This provides a new approach for the development of next generation of ground data transmission structure for data relay satellite system.
