LONDON April 29, 2010 Northrop Grumman Corporations (NYSE: NOC) Europe-based air traffic management subsidiary, Northrop Grumman Park Air Systems, has been awarded a multi-million dollar contract by Air Traffic Control the Netherlands (LVNL) for the nationwide upgrade and renewal of the air traffic control communications infrastructure serving ATC centres and civil airports in the Netherlands. The digital end-to-end voice communication system will consist of Northrop Grummans GAREX 220 switching systems and PAE T6 air-ground radios at Amsterdam Airport Schiphol, Rotterdam the Hague Airport, Groningen Airport Eelde, and Maastricht Aachen Airport and their associated radio ground stations.
