摘要
中继卫星的数据传输主要是合理分配其星载天线资源接受各类数据并进行传输,为了提高接收多用户航天器数据的速度和实时传输能力,需要对星间链路的建立及天线资源分配等相关问题进行研究。首先对中继卫星与用户航天器之间建立星间链路的平台可见性条件进行了分析,提出了计算平台可见的一种简单算法。重点研究了中继卫星用于与多用户航天器之间建立星间链路的天线资源分配问题,提出了中继卫星天线资源分配策略,建立了相应模型并给出了求解算法。最后利用Matlab进行仿真,仿真结果表明所建模型及所提出的几种算法是合理的,可以为中继卫星的任务规划提供服务。
The data transmission of relay satellite is a reasonable allocation of its satellite antenna resources for receiving and transmitting all types of data. In order to enhance multi - user spacecraft real - time data transmission speed and capacity, the establishment of inter- satellite links（ISL） and the antenna resource allocation, issues need to be studied. This paper analysed the condition of platform visibility that established the ISL between the relay satellite and user spacecraft, and a simple algorithm to compute platform visibility was provided. Based on that this paper studied the problem of the ISL＇s Antenna Resources Allocation, a strategy of Antenna Resourses Allocation was provided, a relevant model was established and a solution algorithm was provided. This paper carried out the simulation with Matlab finally, and the simulation result indicates that the model and algorithms provided in this article are reasonable, can support the task planning for relay satellite.
