Abstract
The use of ADS-B to determine safe navigation of airspace is an important feature in the upgrade of the FAA NAS. This upgrade to the NAS will provide a far more accurate location system for aircraft, allowing safer and closer separations in the airspace. At the same time, reduction of the use of radars will allow the FAA to decommission old, costly to maintain radars. ADS-B transmits the location of the transmitter, using the navigation system of the aircraft. An adversary can use the system against itself by transmitting false locations, or transmitting many false ADS-B messages with arbitrary locations, making the airspace seem unsafe for travel. In addition to the ability to create a safer airspace, the system's future includes TIS-B. TIS-B has the potential for significant improvement over the old TCAS system, allowing dangerous situations to be dealt with by the pilot, preventing a mid-air collision. Spoofed targets could cause pilots to take dangerous actions in response to non-existent potential collisions. The goal of this work is the fast determination of whether an ADS-B reporter can quickly be determined to be false, and then to locate the position of the transmitter accurately enough that it can be engaged.
