Swedish Company Shipping VDL Mode 4 Ground Stations
Built on MontaVista Linux Carrier Grade Edition

Sunnyvale, Calif., and Linköping, Sweden, July 29, 2003 — MontaVista Software, Inc., the company powering the embedded revolution, and C.N.S. Systems AB, which develops and markets systems for communication, navigation and surveillance for civil aviation, maritime and land markets, today announced that MontaVista® Linux® Carrier Grade Edition (CGE) 3.0 is the chosen operating system for the data management, and monitoring and control subsystems in the new VDL 4000/GS I ground station from C.N.S.

The VDL 4000/GS I is part of an integrated system for surveillance, navigation and communication services between ground stations and mobile units, or among mobile units that are either mounted in aircraft or in vehicles operating in airport areas. All C.N.S. products for aviation are based on the VDL Mode 4 digital radio link, which is a new standard for air traffic control in Europe.

“MontaVista Linux Carrier Grade Edition provided us with a robust and stable platform and enabled us to get to market in an extremely short time period, ” said Tommy Bergström, chief technology officer, C.N.S. Systems. “We also appreciated MontaVista Software’s great regional support and the fact that CGE has been validated to work seamlessly with our chosen hardware platform — Force Computer’s CPCI-735 board.”
