The Colorado Department of Transportation has launched a new technology initiative that will provide enhanced surveillance, and thereby improve access, to its many mountain airports. Currently, IFR flight operations at those locations are limited because surrounding mountains block the line-of-sight signals of the FAA’s ATC secondary (transponder interrogating) radars, preventing the monitoring of lower-level arriving and departing traffic.
The FAA placed production orders for 11 of Sensis’ airport surface detection equipment systems, Model X (ASDE-X). This requisition is 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, is worth approximately $35 million.
Sensis is building on its experience of automatic dependent surveillance-broadcast (ADS-B) in the FAA-sponsored Capstone trials in Alaska and the increasing use of its multilateration technology with the development of a 1,090-MHz receiver that is under consideration for deployment on the U.S. East Coast and preparations to deploy a multilateration system at Juneau, Alaska.
The FAA recently added new Safety Logic runway incursion alerting technology to its ASDE-X airport surveillance equipment at Orlando International Airport in Florida. ASDE-X combines radar scanning with a transponder tracking system to provide controllers with a real-time picture of airborne and airport surface traffic.
Airport surface detection equipment model X (ASDE-X), designed to help controllers spot potential runway collisions, will be installed at 15 airports beginning with Seattle-Tacoma International Airport next month.
