Global navigation satellite system spoofing detection using weather radar data

A computing device for detecting spoofing of a satellite-based navigation system in a vehicle, the computing device comprising:

• one or more memories;
• and
• processing circuitry coupled to the one or more memories and configured to:
• receive, via a receiver device of the satellite-based navigation system, location data;
• determine an expected future location of the vehicle based on the location data;
• receive, from an external computing device via a communication link, first weather data;
• determine, based on the first weather data, a first weather event for the expected future location;
• determine, based on second weather data received from a weather radar onboard the vehicle, a second weather event;
• determine a correlation between the first weather event and the second weather event;
• and
• in response to the correlation between the first weather event and the second weather event failing to satisfy a threshold, output an indication that the location data received by the receiver device of the satellite-based navigation system is inaccurate.

A computer-readable storage medium storing instructions that when executed by one or more processors cause the one or more processors to:

• receive, via a receiver device of a satellite-based navigation system in a vehicle, location data;
• determine an expected future location of the vehicle based on the location data;
• receive, from an external computing device via a communication link, first weather data;
• determine, based on the first weather data, a first weather event for the expected future location;
• determine, based on second weather data received from a weather radar onboard the vehicle, a second weather event;
• determine a correlation between the first weather event and the second weather event;
• and
• in response to the correlation between the first weather event and the second weather event failing to satisfy a threshold, output an indication that the location data received by the receiver device of the satellite-based navigation system is inaccurate.
