卫星通信链路设计方法与实例研究

Research on design method and example of satellite communication link

卫星通信链路设计是指根据卫星通信系统网络结构和业务需求所提出的卫星网络的可用度和误比特率等性能要求,对卫星链路进行设计和计算,以确定卫星地面站的天线口径、发射功率,以及载波特性的方法。文章对卫星链路设计基本概念和方法进行了介绍,并通过一个实例介绍了一款链路设计的软件,对卫星通信网络规划设计工作具有较强的实际指导意义。

Satellite communication link design is the method for designing and calculating of satellite links to determine antenna aperture,transmitting power and carrier characteristics of satellite ground station according to the requirements of availability and bit error rate performance proposed by satellite communication system network architecture and business demand.In this paper,the basic concepts and methods of the satellite link design are introduced,and an example is given to introduce a kind of software link design,which has a strong practical guiding significance for the satellite communication network planning and design work.
