摘要
针对传统卫星通信系统中跳波束时隙资源以固定预分配的方式由地面控制中心上注,缺乏实时性和灵活性。本文基于VXWorks操作系统设计了低轨宽带星载管理软件,根据功能需求对软件应用层进行设计,并根据功能模块划分多个任务。多任务协同工作,实现根据用户申请资源实时按需进行时隙分配并进行跳波束通信。最终进行在轨通信测试,实验结果满足设计要求。
In the traditional satellite communication system,beam hopping time slot resources are registered by the ground control center in a fixed pre-allocation manner,which lacks real-time and flexibility.Based on the VXWorks operating system,this paper designs the low-orbit broadband spaceborne management software,designs the software application layer according to the functional requirements,and divides multiple tasks according to the functional modules.Multi-task cooperative work to realize real-time and on-demand time slot allocation and beam-hopping communication according to the user’s application for resources.Finally,the on-orbit communication test is carried out,and the experimental results meet the indicators.
