Internet-Based GNSS Signal Authentication

Dinesh Manandhar

Abstract: GNSS spoofing has become a serious issue for security, safety and automation-related applications. GNSS signal authentication is one of the effective methods to detect spoofing attacks. However, it may not be possible to implement signal authentication for existing signals such as GPS L1C/A. This paper describes how an internet-based GNSS signal authentication can be used to authenticate GPS, QZSS, Galileo, BeiDou, and SBAS signals. The advantage of an internet-based signal authentication system is that it can be implemented to existing GNSS signals signal without modifying anything at the space segment.
