摘要
GNSS广泛地应用于各行各业,但是存在卫星导航信号落地功率低,极易受到各种有意和无意的电磁干扰影响,会对卫星导航应用造成严重的威胁.随着卫星导航的广泛应用,卫星导航信号受干扰问题引起了国际的广泛关注.全球卫星导航系统国际委员会(International Committee on Global Navigation Satellite Systems,ICG)为此成立了专门的卫星导航干扰检测与削弱(IDM)工作组,旨在开展各国在该领域的政策法规、相关技术及IDM系统建设的研讨与交流.本文介绍和分析了ICG IDM的重要进展及研究态势,并对干扰检测定位理论技术及国内外卫星导航干扰监测系统的研究进展进行了梳理,对深化卫星导航干扰监测的理论与技术研究及保障卫星导航安全具有重要的技术借鉴与研究支撑.
Global Navigation Satellite System(GNSS)is widely used in all walks of life.However,GNSS signals are very weak and the civilian signal format is known,making it extremely susceptible to various intentional and unintentional electromagnetic interferences,which poses a serious threat to GNSS applications.GNSS interference has attracted widespread international attention,the International Committee on Global Satellite Navigation Systems(ICG)has established a special GNSS interference detection and mitigation(IDM)working group to develop IDM technologies and exchange ideas on IDM system construction.This paper introduces the situation of ICG IDM,and analyzes the research progress of GNSS interference detection and localization technology and IDM systems.It provides important technical reference and research support for deepening the theoretical and technical research on GNSS interference monitoring and ensuring the safety of satellite navigation.
