Abstract:
In some examples, a system, configured to mount on an ownship vehicle, includes a transceiver configured to receive positioning signals and receive surveillance signals including surveillance data from a second vehicle and processing circuitry configured to determine a location of the ownship vehicle based on the positioning signals received by the transceiver and determine expected characteristics of the surveillance signals based on the surveillance data. In some examples, the processing circuitry is further configured to compare the expected characteristics and actual characteristics of the surveillance signals received from the second vehicle and determine that the surveillance signals include a discrepancy indicative of false positioning signals in response to comparing the expected characteristics and the actual characteristics. In some examples, the processing circuitry is configured to output an alert signal indicating the false positioning signals in response to determining that the surveillance signals include a discrepancy.

Claim (Index 21):
A system, configured to mount on an ownship vehicle, the system comprising:\n a transceiver configured to:\n receive positioning signals; and \n receive surveillance signals from a second vehicle; \n receive surveillance signals from a third vehicle; and \n processing circuitry connected to the transceiver, wherein the processing circuitry is configured to:\n determine a location of the ownship vehicle based on the positioning signals received by the transceiver; \n determine that the surveillance signals received from the second vehicle include a discrepancy; \n determine that surveillance signals received from the third vehicle do not include a discrepancy; \n determine that the second vehicle is closer than the third vehicle to the ownship vehicle; \n determine that the second vehicle received false positioning signals from an attacker, in response to:\n determining that the surveillance signals received from the second vehicle include a discrepancy; \n determining that the surveillance signals received from the third vehicle do not include a discrepancy; and \n determining that the second vehicle is closer than the third vehicle to the ownship vehicle; and \n \n output an alert signal indicating the false positioning signals in response to determining that the surveillance signals received from the second vehicle include a discrepancy.
