Luftfartsverket Selects Sensis Wide Area Multilateration for Sweden's Air Traffic Control Surveillance Infrastructure

EAST SYRACUSE, N.Y., March 8, 2011 /PRNewswire/ -- Luftfartsverket (LFV), the air navigation service provider (ANSP) for Sweden, has selected Sensis Corporation's Wide Area Multilateration (WAM) for surveillance of Sweden's airspace. Sensis WAM will be deployed across Sweden to complement and replace the country's Monopulse Secondary Surveillance Radar (MSSR) infrastructure with technology that is compatible with today's avionics while providing the foundation for the growing use of Automatic Dependent Surveillance – Broadcast (ADS-B).

Sensis will deploy separate WAM systems in the Stockholm terminal movement area (TMA) and in a large part of the northern area of the country, with options to deploy additional systems providing nationwide coverage. The goal of the LFV WAM program is comprehensive coverage of the LFV area of responsibility. Sensis WAM will support Mode A/C, Mode S, and ADS-B 1090 ES. The system will provide surveillance from low levels in the Stockholm TMA up to 66,000′ according to coverage requirements. The Sensis solution will employ the same sensor technology that is currently in operation for surface surveillance at Stockholm Arlanda International Airport.

"The Sensis WAM solution provides LFV with the best technological approach to complement and replace our secondary surveillance infrastructure for current and future operating requirements," said Anders Andersson, LFV Project Manager. "This system will enable Mode S and ADS-B possibilities for LFV and have a lower initial acquisition and lifecycle cost than radars while providing our controllers with the same or better surveillance of aircraft in Swedish airspace, including some rural areas that were not previously served by radar."

Sensis multilateration uses multiple low-maintenance, non-rotating sensors to triangulate aircraft locations based on transponder signals to provide 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, Sensis multilateration provides effective surveillance for increased safety, capacity and efficiency of airspace. By employing advanced processing techniques, a Sensis multilateration system uses the minimal number of sensors for a less complex, lower lifecycle cost solution. Additionally, each multilateration sensor deployed by Sensis supports ADS-B, providing an infrastructure for today's surveillance needs and tomorrow's avionics. Almost 100 sites worldwide have chosen Sensis multilateration for airport surface surveillance, wide area surveillance and airport surface management.

"LFV's deployment of Sensis WAM for the complement and replacement of MSSR will be the largest nationwide use of wide area multilateration and further positions the technology as the primary transitional bridge to ADS-B," said Ken Kaminski, vice president and general manager of Sensis Air Traffic Systems. "Sensis' highly deployable, reliable WAM system meets the tough operating requirements set forth by LFV in its plans for the next generation of secondary surveillance."
