基于EPFD分析的高低轨卫星角度间隔研究

Research on angular separation of geostationary and low earth orbit satellites based on EPFD analysis

摘要:

随着低轨(LEO)通信卫星业务需求的增加，低轨卫星需要使用Ka频段进行通信。本文针对低轨卫星采用Ka频段可能与在轨的高轨卫星发生同频干扰问题，采用基于链路分离角的空域分隔方法进行干扰规避的角度间隔分析。分别从不同干扰场景、地面站分布情况来分析对干扰角度间隔的影响，并在此基础上提出该角度间隔范围内，低轨卫星需采取的干扰规避措施。

Abstract:

With the increasing demand of Low Earth Orbit(LEO) communication satellite services, LEO satellites need to use Ka band for communication. In order to solve the problem of co-frequency interference between LEO satellite and Geostationary Orbit(GEO) satellite when Ka band is utilized, the spatial separation method based on link separation angle is adopted to analyze the angle interval of interference avoidance. The influence of different interference scenarios and ground station distribution on the interference angle interval is studied, and the interference avoidance measures are put forward for LEO satellites within the angle interval.
