Sensis A Leader in Wide Area Multilateration

August 19, 2008

Sensis multistatic dependent surveillance (MDS) provides low cost, high performance wide area runway monitoring and terminal area surveillance.


EAST SYRACUSE, NY /PRNewswire/ -- Sensis Corporation's multilateration technology, Multistatic Dependent Surveillance (MDS), has been chosen by eight Air Navigation Service Providers (ANSP) around the world to meet diverse wide area surveillance challenges. MDS provides highly accurate and reliable surveillance in areas where traditional radar is too costly or not practical. MDS is also deployed as a new surveillance solution to challenges such as Precision Runway Monitoring (PRM) and enhanced TMA coverage.

Sensis MDS uses low-maintenance, non-rotating sensors to triangulate/multilaterate aircraft location based on transponder signals and provides air traffic controllers with precise aircraft position and identification information regardless of weather conditions. MDS's flexible design and advanced software algorithms enables Sensis to deploy a system that uses an optimal number of ground stations for reduced cost and complexity. With a higher update rate and greater position accuracy than traditional surface movement radar, Sensis MDS' distributed sensor system provides seamless, consistent, accurate surveillance performance from the airport gates to wide area and en-route as required by the application.

Sensis multilateration is providing solutions to a number of different wide area surveillance projects, including:

  • Precision Runway Monitoring (PRM). Sensis MDS is being deployed at Detroit Metro Wayne County Airport, Michigan and Sydney Airport, Australia for simultaneous approaches to closely spaced parallel runways, demonstrating that MDS meets the high update rate and accuracy demanded by PRM.

     

  • Terminal area surveillance. At Innsbruck Airport, Austria, Sensis MDS is eliminating gaps in coverage caused by terrain and other factors that traditional radar cannot overcome. Sensis MDS is also being deployed for terminal area surveillance at Vancouver Harbor, Canada for surveillance of low flying sea plane traffic; at Ft. St. John, Canada to handle the increased general, commercial and helicopter traffic; and through the FAA WAM Program in Colorado for coverage around Rifle and Hayden Airports and for separation of aircraft around Juneau, Alaska.

     

  • Special Use Airspace (SUA). Sensis MDS is in use at 29 Palms Marine Corps Air Ground Combat Center, California, and the U.S. Navy Patuxent River Naval Air Station, Maryland, and is being deployed at Yuma Proving Grounds, Arizona, to meet the unique surveillance challenges posed by military ranges such as tracking complex, high-speed maneuvering aircraft and low altitude test aircraft, surveillance of commercial air traffic entering the SUA region and rugged environments.

     

  • En-route surveillance. Sensis MDS enables ANSPs to cost-effectively provide en-route surveillance in areas that traditional radar does not serve, significantly enhancing safety and reducing separation standards for more efficient flights. Deployments are ongoing at Tasmania, Australia, and the North Sea, United Kingdom.

"We are seeing a greater acceptance of multilateration for wide area surveillance, particularly in places where traditional surveillance does not exist and as a cost-effective, modern solution for PRM," said Tony Lo Brutto, Vice President and General Manager of Sensis Air Traffic Systems. "Sensis MDS not only delivers the highly accurate surveillance needed for these applications, it's also an economical solution since MDS uses lightweight, non-rotating sensors that are easily deployed and require little maintenance. In addition, each sensor supports ADS-B."
