“…This method requires a highly specialized antenna array and embedded processing. In [4], the authors focused on a robust and precise car navigation system, which can also be used in GNSS-denied or spoofed environments. The system is based and designed for so-called on-board units, which are already used for professional road toll and tracking applications.…”

Electronic attacks such as spoofing are becoming an increasing threat for satellite-based navigation receivers.The aim of this paper is to develop a preventive method against such electronic attacks. In our scheme, the localization system uses four different Global Navigation Satellite Systems (GNSSs): GPS, Galileo, GLONASS, and Compass. The signals received from these satellite systems will be fused inferentially and will be tracked according to a linear model.The linear model that we developed is solved with a Kalman filter and simulated under different scenarios. When a discrepancy is detected in the output of one of the GNSS receivers due to spoofing, it is excluded from the fusion.
