Abstract
A method includes, by a mobile device, receiving a Global Navigation Satellite System (GNSS) signal, and receiving, from a wireless device, via a PC5 interface, a message including a location of a reference structure, a calculated location of the mobile device, or a combination thereof. The method also includes determine whether the GNSS signal is a spoofing signal based on: a spoof indication of the GNSS signal, and whether a difference between a location of the mobile device determined based on the GNSS signal and one of the location of the reference structure, the calculated location of the mobile device, or a location of the mobile device determined based on the location of the reference structure is greater than a threshold value.
