Air Traffic Simulator for Passive ADS-B Surveillance System

Abstract

This contribution presents a concept of a hybrid air traffic simulator which will be used for ADS-B message validation algorithm testing. These validation algorithms will be used in a passive ADS-B surveillance system. In real life, it is not possible to experiment with data communication disruption of an air traffic by injecting spoof targets. It could lead to endangerment of people in aircrafts and even whole air traffic control. It is thus necessary to realize such attacks on data communication only in a simulated environment. Before attempting to create such environment, appropriate and thorough specification is needed. Simulation of an aircraft transponder can be very complex and may not entirely correspond to the behavior of real transponders. Because of that, the simulator will be using real captured data from ground stations in addition to simulated airborne targets.
