FAA Orders Sensis Production of Additional 11 Airport Surface Detection Equipment Systems, Model X

DEWITT, NY - February 11, 2004 - Sensis Corporation today announced that the Federal Aviation Administration (FAA) has exercised production orders for 11 Airport Surface Detection Equipment Systems, Model X (ASDE-X). The systems are in addition to the 21 initial systems ordered in December 2002. The production option for the 11 ASDE-X systems, in addition to associated hardware, software and support, has an approximate value of $35M.

ASDE-X is an airport surface surveillance system for the airport surface that will provide seamless surveillance and aircraft identification to air traffic controllers. The system uses a combination of surface movement radar, transponder multilateration and ADS-B sensors to display aircraft position, labeled with flight call signs, on air traffic control tower displays. The integration of the three components provides data with an accuracy, update rate and reliability that will improve airport safety and efficiency.

“ASDE-X is a very important safety related program with direct benefits to the flying public and the airlines,” said Marc Viggiano, president of Sensis Air Traffic Systems. “It’s very gratifying to see the program continue to progress, and Sensis looks forward to remaining in close coordination with the controllers and airway facilities specialists to ensure a smooth integration into the National Airspace System.”

Under the ASDE-X program, the FAA will deploy ASDE-X at 34 of the nation’s busiest airports. The system was declared ready for national deployment in October 2003 when it was commissioned at General Mitchell International Airport in Milwaukee, WI. In addition to the 34 airports, the FAA also is looking at the possibility of adding ASDE-X technology to 25 airports that now have ASDE-3 ground radars coupled with the Airport Movement Area Safety System (AMASS). This modification will improve the overall surveillance by adding multilateration capabilities, giving 59 of the nation’s busiest airports a common surface-surveillance technology.

Sensis’ multilateration technology is also in operational use at London Heathrow Airport and is being installed at seven additional European airports - Brussels Airport (Belgium); Charles de Gaulle Airport (France); Frankfurt Airport (Germany); Geneva International Airport (Switzerland); Amsterdam Airport Schiphol (The Netherlands); Vienna International Airport (Austria); and Zurich Airport (Switzerland).

In a separate press release issued today, Sensis announced that the FAA has tasked Sensis to develop system enhancements to the Airport Surface Detection Equipment, Model X (ASDE-X) program.
