摘　　要：近年来卫星通信向大容量、宽带化方向发展,数据传输高效调度技术的研究成为热点。文章对卫星AOS数据传输中通道资源使用情况进行分析,提出了一种数据传输高效调度方案,该方案通过高效利用数据传输中的无效间隙,提高数据传输通道利用率。经理论分析、FPGA仿真以及硬件测试验证表明,使用所提调度方案后数据传输通道中有效数据占比优于99.99%。高效调度方案较原有数据传输方案能更有效的利用卫星数据传输通道,为卫星数据高效传输提供了一种新的技术途径。In recent years,satellite communication has been developing in the direction of large-capacity and broadband,and research on efficient scheduling technology for data transmission has become a hot spot.The article analyzes the use of channel resources in satellite AOS data downstream,and proposes an efficient scheduling scheme that can greatly improve the utilization rate of satellite transmission channels by efficiently using the invalid data gaps.The results of theory analysis,FPGA simulation and hardware test verification show that the effective data ratio in the data transmission channel is better than 99.99%after the scheduling scheme is applied.The efficient scheduling scheme can use the satellite data transmission channel more effectively than the original scheme,which provides a new technical approach for the efficient transmission of satellite data.
