摘要

在目前非对地静止轨道（NGSO）卫星移动业务用频越来越紧张的趋势下，针对手机直连NGSO卫星业务频率协调工作复杂的问题，首先对手机直连NGSO卫星系统的用频现状及趋势进行分析，其次重点对手机直连NGSO卫星业务在扩展L频段和其他同频空间业务的频率协调方案进行分析和研究。通过分析手机直连 NGSO 卫星业务在扩展 L 频段的频率协调态势确定需要与之开展频率协调工作的空间业务，基于和每一项空间业务的频率协调方案进行研究并给出协调方案建议，同时还对具体协调方案中涉及的干扰分析计算进行举例。以上研究均可作为手机直连NGSO卫星业务系统开展同频频率协调相关研究及下一步手机直连NGSO卫星关键技术研究等相关工作的参考。

Abstract

At present

the frequency of non-geostationary orbit(NGSO) mobile satellite service is becoming more and more tense.Aimed at the complicated problem of frequency coordination of mobile direct connection to NGSO satellite service

firstly

an analysis was conducted on the current frequency usage status and trends of mobile direct connection to NGSO satellite service.Secondly

the frequency coordination scheme between mobile direct connection to NGSO satellite service and other same frequency space services in extended L-band was analyzed and studied.By analyzed the frequency coordination of mobile direct connection to NGSO satellite service in extended L-band

the space services that need to carry out frequency coordination work with mobile direct connection to NGSO satellite service were determined.The basic frequency coordination scheme of mobile direct connection to NGSO satellite service with each space service was studied and the coordination scheme suggestions were given

at the same time

the interference analysis and calculation involved in the specific coordination scheme were listed for example.The above research can be used as reference for the research of frequency coordination of mobile direct connection to NGSO satellite service system

as well as for the next step research of key technologies related to mobile direct connection to NGSO satellite service.
