Sensis Surface Multilateration System at London Stansted Airport Now Operational

Controllers at Stansted now have the same surveillance capabilities as Heathrow and Gatwick to effectively and safely manage surface traffic in all weather, said Alistair Clark, NATS program manager. Additionally, using the same surveillance platform across three key airports is cost-effective for NATS as it simplifies training and maintenance. Sensis multilateration uses multiple low-maintenance, non-rotating sensors to triangulate aircraft and vehicle 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. With its 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 Automatic Dependent Surveillance Broadcast (ADS-B). NATS has shown great confidence in Sensis and its technologies as were now providing surveillance for three critical airports that handle over 124 million passengers per year, said John Jarrell, vice president and general manager of Sensis Air Traffic Systems. Sensis multilateration can be easily expanded to accommodate future airport growth, which recently occurred at London Heathrow as the existing Sensis system was augmented with additional sensors to ensure coverage surrounding the new Terminal 5. Almost 100 sites worldwide have chosen Sensis multilateration to enhance safety, efficiency, capacity and cost savings through airport surface surveillance, wide area surveillance and airport surface management.
