Air navigation service provider, Luftfartsverket (LFV) has chosen the Wide Area Multilateration (WAM) from Sensis Corporation for supervision of Sweden's airspace.
Replacing Sweden’s Monopulse Secondary Surveillance Radar (MSSR), the WAM systems will be deployed in the northern regions and in the Stockholm terminal movement area (TMA).
The objective of the LFV WAM program is an all-inclusive coverage of the company’s region of responsibility. Sensis WAM can be used with modern day avionics and offers surveillance from lower levels to about 66,000’. Compatible with Automatic Dependent Surveillance, the Broadcast (ADS-B), the system supports ADS-B 1090 ES, Mode S and Mode A/C. The Sensis system uses the sensor technology that is presently employed for surface supervision at the Stockholm Arlanda International Airport.
Approximately 100 locations worldwide have selected the Sensis technology for wide area/airport surface surveillance and airport surface management.
The Project Manager at LFV, Anders Andersson stated that the system will have a lower lifestyle cost and initial acquisition as compared to other radars.
Using non-rotating, low-maintenance sensors, the Sensis multilateration triangulates aircraft position based on transponder signals and provides air traffic controllers with highly accurate aircraft position and identification data in any weather condition. With greater update rates and positional precision, Sensis WAM ensures better safety, efficiency and capacity of airspace.
