Abstract
System and method to protect the privacy of ADS-B messages transmitted by aircraft. The system includes one or more ground stations with a ground station control unit and a ground ADS-B transponder for receiving an ADS-B message. The ground station control unit includes an aircraft position determination module for retrieving an aircraft position included in the ADS-B message; an operating conditions module for determining the fulfillment of operating conditions including determining if the aircraft position is an actual aircraft position; and a fake aircraft position generator for computing one or more fake aircraft positions. The ground station control unit broadcasts one or more fake ADS-B messages including the fake aircraft positions if the operating conditions are met. With this system only trusted receivers can obtain the real position of the aircraft.
