Claim 9:
10. A system comprising:
one or more processors configured to examine examining positional data signals received onboard a vehicle from one or more off-board communication devices, wherein the positional data signals are received by a first antenna of a first Global Navigation Satellite System (GNSS) receiver and a second antenna of a second GNSS receiver onboard the vehicle, and the one or more processors are configured 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,
the one or more processors configured to identify inaccurate positioning data in the positional data signals based on the one or more characteristics in the positioning data that are identified, the one or more processors configured to identify the inaccurate positioning data responsive to the strengths of the positional data signals increasing or decreasing by more than a designated threshold value;
the one or more processors are configured to receive the positional data signals via the first antenna of the first GNSS receiver, the one or more processors are configured to receive additional positional data signals via the second antenna of the second GNSS receiver, the one or more processors are configured to examine 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 received at the first antenna and the additional positional data signals received at the second antenna, the one or more processors are configured to identify a first communication device of the one or more off-board communication devices as a spoofing device or a jamming device responsive to the increases or the decreases in the strengths of one or more of the positional data signals or the additional positional data signals received at the first antenna increasing or decreasing by more than the designated threshold value while the increases or the decreases in the strengths of the one or more of the positional data signals or the additional positional data signals received at the second antenna do not increase or decrease by more than the designated threshold value.
