摘要/Abstract

摘要： 星间链路是现代卫星导航系统的主要技术特征之一。针对星间链路条件下卫星导航系统业务数据传输规划调度问题，设计了一种规划调度数学模型，并在此基础上提出了启发式规划调度方法。基于北斗三号卫星导航系统的场景设置，对该方法进行了仿真验证。仿真结果表明：启发式规划调度方法能在北京、新疆和海南3个地面站组成的区域监测网条件下成功实现卫星导航系统30颗卫星的业务数据传输规划调度，调度结果满足卫星导航系统任务需求；各任务周期内平均需要地面站天线15.375个，且绝大部分地面站资源利用率超过70%.

Abstract: The inter-satellite link is one of the main technical features of modern satellite navigation systems. A scheduling mathematical model is designed for the service information transmission scheduling problem of satellite navigation system with inter-satellite link. Based on this, a heuristic scheduling algorithm is proposed. Based on scene settings of Beidou-3 satellite navigation system, the model and algorithm are simulated and verified. The simulated results show that the proposed method can be used to schedule the service information transmission of 30 satellites in the satellite navigation system under the condition of regional monitoring network consisting of three ground stations in Beijing, Xinjiang and Hainan. And the scheduling results satisfy the mission requirements of satellite navigation system. The average number of ground station antennas is 15.375 in each mission period, and the utilization rate of most ground station antennas is over 70%. Key
