Method for Detecting GNSS Spoofing in a GNSS Receiver of a Localization System

A method for detecting global navigation satellite system ("GNSS") spoofing in a GNSS receiver of a localization system includes a) detecting ephemeris data or almanac data of a GNSS satellite in a time step, and b) detecting ephemeris data or almanac data of the same GNSS satellite in a s...

Zusammenfassung:	A method for detecting global navigation satellite system ("GNSS") spoofing in a GNSS receiver of a localization system includes a) detecting ephemeris data or almanac data of a GNSS satellite in a time step, and b) detecting ephemeris data or almanac data of the same GNSS satellite in a subsequent time step. The method also includes c) comparing the ephemeris data or almanac detected in step a) with the ephemeris data or almanac data detected in step b), and d) detecting the GNSS spoofing when the ephemeris data or almanac data detected in step a) and in step b) deviate from each other.
