Abstract
A method, a system, and computer readable medium for detecting interference with a navigation system are provided. The method includes detecting a global positioning system (GPS) signal via the navigation system of a vehicle, determining a signal strength of the GPS signal, determining a location of the vehicle based on the GPS signal, and determining a first attribute and a second attribute. The first attribute is determined as a function of the signal strength. The second attribute is determined as a function of the location of the vehicle. The method further includes outputting an alert indicating an interference with the navigation system when the first attribute and the second attribute are true.
