Abstract
An autonomous vehicle, system and method of operating an autonomous vehicle. The system includes a communication module and a processor. The communication module sends a first set of Global Positioning Satellite (GPS) data over a first communication channel and a second set of GPS data over a second communication channel. The second set of GPS data is an authenticated data set. The processor operates the autonomous vehicle using the first set of GPS data, and compares the first set of GPS data to the second set of GPS data to verify the integrity of the first set of GPS data. A first value for a vehicle parameter based on the first set of GPS data is compared to a second value for the vehicle parameter based on data from a vehicle-based sensor. The first set of GPS data is rational when the difference is less than a selected threshold.
