卫星导航欺骗及检测(三):基于辅助信息的欺骗检测

GNSS spoofing and detection(Ⅲ):spoofing detection technology based on auxiliary information

简单介绍了相对位置已知的多天线欺骗检测技术和视觉、磁强计等其他传感器辅助的导航欺骗技术;详细论述了基于惯性导航辅助信息的卫星导航欺骗检测技术的研究现状和发展动态,指出可以利用惯性导航短时间精度较高的特性对卫星导航欺骗进行检测;最后,对基于辅助信息的欺骗检测技术发展趋势和应关注的研究方面进行了展望。

The multi-antenna spoofing detection techniques known for relative position and other sensor-assisted spoofing techniques such as vision and magnetometer are briefly introduced;the research status and development of Global Navigation Satellite System(GNSS)spoofing detection techniques based on inertial navigation information aids are discussed in detail,and it is pointed out that inertial navigation can be used to detect spoofing with high accuracy for a short period of time;finally,the development trend of GNSS spoofing detection techniques based on aids and the research aspects that should be paid attention to are outlined.
