[Avionics Today 10-08-2015] Thales has signed a contract to provide two Wide Area Multilateration (WAM) systems for the Terminal Maneuvering Area of Siem Reap and Phnom Penh airports in Cambodia. Cambodia Air Traffic Services (CATS), a subsidiary of SAMART Corporation, a Thai ICT group, will operate the systems. CATS provides air traffic control services to both civil and military airspace, throughout Cambodia.
Thales has designed the WAM systems to maximize use of the existing Air Traffic Management (ATM) infrastructure for CATS. Through this contract, the existing Thales Automatic Dependent Surveillance-Broadcast (ADS-B) ground stations will become an integral part of the WAM systems. The systems will process and display surveillance data from all sensors at the Thales TopSky-ATC system in Phnom Penh. In addition, the WAM systems will help optimize air traffic across Cambodian airspace, hence reducing aviation-related CO2 emissions.
