Determining a location of a vehicle using received surveillance signals

A method comprising:

• receiving, by a first receiver mounted on an ownship vehicle at a first time, a surveillance packet from another vehicle;
• receiving, by a second receiver mounted on the ownship vehicle at a second time, the surveillance packet from the other vehicle;
• receiving, by a third receiver mounted on the ownship vehicle at a third time, the surveillance packet from the other vehicle;
• and
• determining a location of the ownship vehicle based on the received surveillance packet and based on the respective arrival times.

A device comprising a computer-readable medium having executable instructions stored thereon, configured to be executable by processing circuitry for causing the processing circuitry to:

• determine a first time at which a first receiver mounted on an ownship vehicle received a surveillance packet from another vehicle;
• determine a second time at which a second receiver mounted on the ownship vehicle the surveillance packet from the other vehicle;
• determine a third time at which a third receiver mounted on the ownship vehicle the surveillance packet from the other vehicle;
• and
• determine a location of the ownship vehicle based on the received surveillance packet and based on the respective arrival times.
