Louisville Airport's ASDE-X Now Operational

Louisville International Airport's ASDE-X (airport surface detection equipment - model X), built by Sensis Air Traffic Systems, is now operational, making it the ninth U.S. airport to have the safety system officially functioning.

ASDE-X uses a combination of surface movement radar, transponder multilateration and ADS-B (automatic dependent surveillance-broadcast) sensors to provide air traffic controllers with an accurate picture of the location and identity of aircraft and vehicles on the airport surface.  In addition, the Sensis system has conflict detection and alerting technology, called Safety Logic, which detects and alerts controllers to potential aircraft and vehicle collision situations.

The FAA is in the process of deploying ASDE-X at 35 U.S. airports.  07-30-2007.
