1. A method for verifying a location of a vehicle, the method comprising:
receiving positional data signals from one or more off-board communication devices, the positional data signals received at a first antenna of a first global satellite system (GNSS) receiver and a second antenna of a second GNSS receiver onboard the vehicle;
examining the positional data signals to identify one or more characteristics in positioning data of the positional data signals, the one or more characteristics including increases or decreases in strengths of the positional data signals;
identifying inaccurate positioning data in the positional data signals based on the one or more characteristics in the positioning data that are identified, the inaccurate positioning data identified responsive to the strengths of the positional data signals increasing or decreasing by more than a designated threshold value;
receiving additional positional data signals at the second antenna of the second GNSS, and
examining the positional data signals and the additional positional data signals by determining the increases or the decreases in the strengths of the positional data signals and the additional positional data signals received at the first and second antennas, wherein at least one communication device of the one or more off-board communication devices is identified as a spoofing device or a jamming device responsive to a change in a strength of the strengths of the one or more of the positional data signals or the additional positional data signals received at one of the first or second antennas increasing or decreasing by more than the designated threshold value while the increases or the decreases in the strength of the one or more of the positional data signals or the additional positional data signals received at the other of the first or second antennas not increasing or decreasing by more than the designated threshold value.
