摘要

梳理全球对地静止轨道（GSO）卫星网络的申报情况、协调数量以及GSO实际在轨卫星情况，研究GSO卫星网络间干扰分析国际计算规则、协调弧和ΔT/T两种判断是否需要开展协调的计算方法、在不同干扰场景下C/I的计算方法以及各输入参数的获取方式，介绍Visualyse GSO和国际电信联盟GIBC两种GSO卫星网络干扰仿真分析软件，用Visualyse GSO软件分析不同轨位间隔情况下GSO卫星网络间的干扰程度。为卫星操作单位进行GSO卫星网络间干扰分析计算、保障卫星频率切实可用提供参考。

Abstract

The status of the submission and coordination of the global geostationary-orbit (GSO) satellite networks

GSO satellites in orbit were reviewed.The international rules of interference analysis and calculation between GSO satellite networks

two calculation methods of judging whether the coordination was needed coordination arc and ΔT/T

the calculation method of C/I and the access of the input parameters under diff erent scenarios were studied.The softwares of Visualyse GSO and ITU GIBC were introduced.The interference using the Visualyse GSO software between GSO satellite networks with different orbital separations was analyzed.It provides a reference for satellite operators to analyze and calculate the interference between GSO satellite networks and ensure the practical availability of satellite frequencies.
