Abstract

signals, and omit these from the position and time computation. The algorithms are evaluated with simulated and live-sky meaconing attacks. The simulated spoofing attacks show that mitigation using pseudoranges is possible in these tests when the receivers are separated by five meters or more. At 20 meters, the pseudorange algorithm correctly authenticates six out of seven pseudoranges within 30 seconds in the same simulator tests. Using carrier phase allows mitigation with shorter distances between receivers, but requires better time synchronization between the receivers. Evaluations with live-sky meaconing attacks show the validity of the proposed mitigation algorithms.

多接收机抑制GNSS欺骗的结果

信号，并从位置和时间计算中省略这些。通过模拟攻击和实时攻击对算法进行了评估。模拟的欺骗攻击表明，在这些测试中，当接收器相距5米或更远时，可以使用伪距离进行缓解。在20米的距离上，在相同的模拟器测试中，伪橙算法在30秒内正确地验证了7个伪橙中的6个。使用载波相位可以减少接收器之间的距离，但需要接收器之间更好的时间同步。对实时威胁攻击的评估表明了所提出的缓解算法的有效性。

期刊介绍： NAVIGATION is a quarterly journal published by The Institute of Navigation. The journal publishes original, peer-reviewed articles on all areas related to the science, engineering and art of Positioning, Navigation and Timing (PNT) covering land (including indoor use), sea, air and space applications. PNT technologies of interest encompass navigation satellite systems (both global and regional), inertial navigation, electro-optical systems including LiDAR and imaging sensors, and radio-frequency ranging and timing systems, including those using signals of opportunity from communication systems and other non-traditional PNT sources. Articles about PNT algorithms and methods, such as for error characterization and mitigation, integrity analysis, PNT signal processing and multi-sensor integration, are welcome. The journal also accepts articles on non-traditional applications of PNT systems, including remote sensing of the Earth’s surface or atmosphere, as well as selected historical and survey articles.
