This paper discusses a global position system (GPS) synchronized wide area multilateration (WAM) system for air traffic management. The system takes advantage of secondary surveillance radar (SSR) downlink mode S/A/C signals on 1090 MHz channel, determines the position of airplane passively by TDOA (time differential of arrival) hyperbolic position method. Also this system has ADS-B (auto-dependent surveillance-broadcast) capability to position those airplanes with onboard ADS-B transponders, and the experimental results of WAM and ADS-B are discussed.
