Austro Control uses nation-wide wide area multilateration system from Saab

1 April 2014

Defense and security company Saab said it has announced that Austro Control, the air navigation service provider for Austria, has placed into operation its nation-wide wide area multilateration (WAM) system from Saab.

The WAM system, covering six Terminal Maneuvering Areas and the entire Austrian FIR plus a zone of 40NM in high density airspace, provides Austro Control controllers with highly accurate, one-second update rate surveillance of flights.

The WAM system is comprised of numerous sensors deployed throughout the country and a central processing system that provides data directly to Eurocontrol´s Air Traffic Management SuRveillance Tracker and Server (ARTAS) where ARTAS correlates WAM data with data from existing radars for a fused output. The WAM system provides one-second surveillance update, an improvement over secondary surveillance radar´s four second update rate. The initial operational use of the system is in the en-route airspace; the terminal area coverage volumes are expected to be integrated into full operational status in 2014.

Saab provides the global defense and aviation markets with advanced sensor technologies, next-generation radars, automation, and modeling and simulation solutions. It serves military, civil aviation, airport and airline customers in more than 40 countries across six continents. Its website is at,, and
