摘要
随着全球卫星导航系统(Global Navigation Satellite System,GNSS)应用于社会生活及军事领域的各个方面,卫星导航安全也日益受到各国重视。卫星导航欺骗式干扰技术因具有较大危害性和高度隐蔽性,逐渐成为影响卫星导航应用的严重威胁,也成为干扰技术研究的热点。本研究从GNSS欺骗器的发展、信号欺骗方法和轨迹欺骗方法3个方面对卫星导航欺骗式干扰关键技术的研究现状进行了梳理,并对卫星导航欺骗式干扰技术的未来发展趋势进行了展望。
As the application of the Global Navigation Satellite System(GNSS)has penetrated into all aspects of social life and military field,satellite navigation safety is also increasingly valued by countries.Due to its great harm and high concealment,satellite navigation spoofing interference technology has gradually become an important threat to satellite navigation applications,and has also become a hotspot of interference technology research.The development of GNSS spoofer,signal spoofing method and trajectory spoofing method are reviewed.Finally,the future development trend of satellite navigation spoofing technology is prospected.
