Patent ID: 11668835

Abstract:
Systems and methods for GNSS spoofing detection using C/No based monitoring are provided. In certain embodiments, a system including at least one GNSS receiver that provides C/No for GNSS signals received from GNSS satellites. The system also includes a processor coupled to the at least one GNSS receiver. The processor executes instructions that cause the processor to calculate new C/No comparison values based on the C/No measurements and previous C/No comparison values. Further, the instructions cause the processor to compare the C/No measurements against the previous C/No comparison values. Moreover, the instructions cause the processor to determine whether one or more of the GNSS signals are spoofed based on the comparison of the C/No measurements against the previous C/No comparison values. Additionally, the instructions cause the processor to set the new C/No comparison values as the previous C/No comparison values.
