基于P(Y)码互相关的GPS信号欺骗检测技术研究

GPS Signal-Spoofing Detection based on P(Y) Code

随着迈入高度信息化的时代,人类对能够提供全球性、全天候、连续性和实时性的高精度三维位置信息的GPS系统的依赖性越来越强。然而,由于GPS信号固有的脆弱性,用户端很容易遭受的欺骗攻击,跟踪捕获到欺骗信号,使得欺骗目标产生错误定位同时还不会引起欺骗目标的察觉。因此,本文提出一种基于P(Y)码互相关的欺骗检测技术,并对其原理进行详细的分析,还列举了基于该技术的应用方案,希望该项技术能对GPS欺骗检测领域发挥重要的作用。

In the era of high informatization,people increasingly rely on GPS system,which could provide global,allweather,continuous and real-time 3D positioning information. However,due to the inherent vulnerability of GPS signals,the clients are prone to spoofing attacks,tracking spoofing signals and acquiring false positioning information,without any notice. Thus a novel spoofing detection technique based on P（Y） code cross-correlation is proposed,its principles exhaustively analyzed,and some involved application schemes also cited,all this may serve as a reference for the research in GPS spoofing detection field.
