模糊聚类方法在GPS欺骗干扰判断中的应用

Applications of Fuzzy Cluster in Judgment of GPS Spoofing Jamming

基于GPS接收机OEM板输出的NMEA0183通信协议中的GSV语句输出可见卫星载波一噪声功率密度比数据，根据受欺骗卫星的载波一噪声功率密度比与正常卫星的载波一噪声功率密度比不同，应用模糊聚类分析方法将受欺骗干扰卫星和正常卫星进行分类。验证表明：该方法能较准确地识别出受干扰的卫星，算法简单；为GPS欺骗干扰判断提供了一种新的途径。

Based on the output C/N0 data of GPS OEM in NMEA0183 GSV format, fuzzy cluster method is used to differentiate out spoofed satellites and normal ones, according to the different C/N0 values between spoofed satellites and normal ones. The result shows that this method can find spoofed satellites in high accuracy and the arithmetic is simple. The method provides a new approach to the judgment of GPS spoofing jamming.
