摘要: 描述了典型数据中继卫星系统的通信链路;给出了这些系统在用的和计划使用的无线电频谱;讨论了影响数据中继卫星频段选择的因素。为了防止其他中继卫星系统对一个中继卫星系统的有害干扰,可以使用如频率错开、极化分辨、经度分离,甚至采用伪码分辨的方法。
关键词: 数据中继卫星
Abstract: n this paper,typical communication links in a data relay satellite system are described,the current and planned uses of the RF spectrum by such systemare presented.Factors affecting frequency selection of data relay satellite bands arealse discussed.In order to prevent from harmful interference from one system to another DRS system,various methods,such as frequency separation,polarization discrimination,longitude separations of neighboring DRS,even CN code discriminationcan be used.
