Automatic Dependent Surveillance-Broadcast (ADSB) is an Air Traffic Control system in which aircraft transmit their own information (identity, position, velocity etc.) to ground sensors for surveillance scope. The tracking of the different sensors' clocks by the use of Time Difference of Arrival of ADSB messages is proposed to check the veracity of the position information contained in the ADS-B messages. The method allows detecting possible on board anomalies or the malicious injection of fake messages (intrusion) without the use of the multilateration (or any other) location algorithm. It follows that it does not need the inversion of the location problem (usually strong non-linear and ill-posed), and, contrary to the multilateration, it works also with less than 4 sensors.

Abstract

Automatic Dependent Surveillance-Broadcast (ADSB) is an Air Traffic Control system in which aircraft transmit their own information (identity, position, velocity etc.) to ground sensors for surveillance scope. The tracking of the different sensors' clocks by the use of Time Difference of Arrival of ADSB messages is proposed to check the veracity of the position information contained in the ADS-B messages. The method allows detecting possible on board anomalies or the malicious injection of fake messages (intrusion) without the use of the multilateration (or any other) location algorithm. It follows that it does not need the inversion of the location problem (usually strong non-linear and ill-posed), and, contrary to the multilateration, it works also with less than 4 sensors.
