Saab wins €3.7 million Croatia air navigation contract


Saab has been awarded a 3.7 million euro contract by air navigation service provider Croatia Control to deliver air traffic surveillance over Croatia through Saab’s Cooperative Surveillance System (CSS). Saab will support flight operations across Croatia, bringing surveillance data into Croatia Control’s own air traffic systems. The CSS uses Wide Area Multilateration (WAM) technology, and Croatia will now have one of the biggest and comprehensive WAM systems in the world. “Saab’s CSS system for Croatia uses the latest version of our WAM technology along with the newest software and sensors, providing accurate and reliable detection of aircraft transponders from take off to landing. The system can easily be expanded to provide seamless coverage through the incorporation of additional remote units without the need for more centralised hardware”, Saab’s CEO in the US, Erik Smith, said. Croatia Control’s Executive Director for Technical Services and Infrastructure, Juraj Maštrović, added, “Our objective is to enhance the existing surveillance system that is currently used to provide safe and efficient Air Traffic Control service in Croatia. We look forward to working closely with Saab and we’re confident that their CSS solution and ability to implement it in due time can help us meet those goals”. Saab’s WAM solutions use multiple, low-maintenance, non-rotating sensors to calculate aircraft locations based on transponder signals. Saab’s solution provides air traffic controllers with precise aircraft position and identification information, regardless of weather conditions. With a higher update rate and greater positional accuracy than traditional radar, Saab’s multilateration provides effective surveillance for increased safety, capacity and efficiency of airspace.

    Nice job for SAAB. Multilateration (MLAT) is not easy to rollout sucessfully.
    Similar project (in preparation phase) is ongoing in Serbia also.

      In Slovenia we have it for years already. Also Austria had it before us.
      It enabled Slovenia to have 3NM separation in lower airspace instead of 5NM.
