GNSS spoofing detection and recovery

A mobile device comprising:

• a transceiver including a PC5 interface;
• a Global Navigation Satellite System (GNSS) receiver;
• a memory;
• and
• one or more processors communicatively coupled with the transceiver, the GNSS receiver, and the memory and configured to:
• receive, via the GNSS receiver, a GNSS signal;
• receive, via the PC5 interface, from a wireless device, a message including a location of a reference structure, a calculated location of the mobile device, or a combination thereof;
• and
• determine whether the GNSS signal is a spoofing signal based on a spoof indication of the GNSS signal;
• and
• perform:
• in response to determining that the GNSS signal is not a spoofing signal based on the spoof indication of the GNSS signal, determining a location of the mobile device based on the GNSS signal;
• or
• in response to determining that the GNSS signal is a spoofing signal based on the spoof indication of the GNSS signal, verifying whether the GNSS signal is a spoofing signal by determining whether a difference between the 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.

A mobile device comprising:

• means for receiving a Global Navigation Satellite System (GNSS) signal;
• means for 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;
• and
• means for determining whether the GNSS signal is a spoofing signal based on a spoof indication of the GNSS signal;
• and
• means for, in response to determining that the GNSS signal is a spoofing signal based on the spoof indication of the GNSS signal, verifying whether the GNSS signal is a spoofing signal by determining 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.

A non-transitory computer-readable medium having instructions embedded thereon which, when executed by one or more processing units, cause the one or more processing units to perform operations including:

• receiving, via a Global Navigation Satellite System (GNSS) receiver of a mobile device, a GNSS signal;
• receiving, from a wireless device, via a PC5 transceiver, a message including a location of a reference structure, a calculated location of the mobile device, or a combination thereof;
• and
• determining whether the GNSS signal is a spoofing signal based on a spoof indication of the GNSS signal;
• and
• in response to determining that the GNSS signal is a spoofing signal based on the spoof indication of the GNSS signal, verifying whether the GNSS signal is a spoofing signal by determining 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.
