载干比在地球静止卫星轨位协调中的应用

Application of C/I for the coordination of the GEO satellite's orbits

在目前的邻星协调方面,国际电联(ITU)推荐2个同频段、共服务区的地球静止卫星之间的最小轨位间隔为3°,结合工程实际,按照国际电联(ITU)推荐的分析方法,结合卫星的具体配置,将载干比用于两颗临近轨位的地球静止卫星的干扰分析,分析结果表明:这两颗卫星的最小轨位间隔可以确保优于3°,从而提高了宝贵的空间轨位资源利用率。

ITU recommend the minimum space orbit distance for the same frequency and service area is three degree. This paper discuss the application of C/I for the coordination of the GEO satellite ＇ s space orbits under the work practice, the analysis shows it is feasible for the minimum space orbit distance less than three degree because of the actual two GEO satellites configuration , improving the usage of the precious GEO satellite＇s space orbits.
