Sensis Airport Surface Surveillance System Enhancing Safety at Lambert – St. Louis International Airport

East Syracuse, NY – July 10, 2006 – Sensis Corporation announced that its Airport Surface Detection Equipment, Model X system (ASDE-X) for the Federal Aviation Administration is operational at Lambert-St. Louis International Airport. On a dense airport surface, aircraft operate in close proximity to vehicles, pedestrians, equipment and buildings. The primary concern in this environment is safety – avoiding potential collisions. ASDE-X provides air traffic controllers at Lambert with a complete picture of the airport surface. The improved situational awareness controllers experience with the system will enable them to more safely guide aircraft and vehicles at the airport.

Sensis ASDE-X uses multiple surveillance sources (surface movement radar, multilateration, ADS-B) that allow for coverage in the most complex airport environment; a sophisticated fusion processor to provide a comprehensive surveillance picture of the airport surface; an integrated display that features an interface developed in full consultation with air traffic controllers; and the world’s most advanced runway incursion safety alerting system, Safety Logic.

“The continued successful deployment of ASDE-X is the result of close collaboration between the FAA and Sensis,” said Marc Viggiano, president of Sensis Air Traffic Systems. “To ensure that the system met the highest safety standards, Sensis partnered with the FAA to satisfy more than 2,000 technical requirements prior to the agency commissioning ASDE-X for use in the National Airspace System.”

In addition to Lambert-St. Louis International Airport, the system is now deployed at ten airports and is operational and commissioned at seven. The FAA is in the process of deploying the ASDE-X system to a total of 35 of the nation’s airports.
