Flight Test Results of a Conflict Detection Method using ADS-B with Raw GNSS Measurements

Pengfei Duan, Maarten Uijt de Haag, James L. Farrell

Abstract:	Future Aircraft Surveillance Applications (ASA) systems such as conflict detection, final approach and runway occupancy, and airport surface situational awareness methods will benefit from the introduction of Automatic Dependent Surveillance-Broadcast (ADS-B). An alternative ADS-B implementation, which transmits raw measurements from the Global Navigation Satellite System (GNSS) instead of aircraft state vectors and performance parameters in the current implementation, was proposed previously to improve surveillance performance. This paper summarizes the proposed methodology, discusses the threat models and integrity aspects of this method, and presents the initial flight test results of this alternative ADS-B implementation, along with a performance analysis of this method.
