Airport Surface Detection Equipment, Model X (ASDE-X) 1
Airport Surface Detection Equipment, Model X (ASDE-X) 1 : ASDE-X is a traffic management system for the airport surface that provides seamless coverage and aircraft identification to air traffic controllers. The system uses a combination of surface movement radar and transponder multilateration sensors to display aircraft position labeled with flight call-signs on an ATC tower display. The integration of these sensors provides data with an accuracy, update rate and reliability suitable for improving airport safety in all weather conditions. This system also features advanced conflict detection and alerting technology, Safety Logic, which uses complex algorithms to alert controllers of potential aircraft and/or vehicle incursions. Further, the system is architected to support Automatic Dependent Surveillance - Broadcast (ADS-B). The FAA has identified?35 airports?in the United States as candidates for ASDE-X systems. In addition to improving safety through?runway incursion prevention, the quality of the ASDE-X data resulting from the fusion of multiple surveillance sources enables decision support for: (1) Positive correlation of flight plan information with aircraft position on controller displays; (2) Seamless surveillance coverage of the airport from arrival through departure; (3) Elimination of blind spots and coverage gaps; and (4) Highly accurate, high update surveillance enabling: (a) situational awareness even in inclement conditions and (b) conflict detection and resolution. Further, continuous growth in U.S. aviation is causing serious capacity problems at many airports, resulting in an increase in system-wide delays and a struggle to maintain adequate safety. The ASDE-X technology will help to alleviate these issues by reducing controller and pilot workload through improved situational awareness. ASDE-X Core Components: The ASDE-X architecture consists of five core components: Multilateration, Surface Movement Radar, Automatic Dependent Surveillance - Broadcast (ADS-B), Multi-Sensor Data Processing, and Tower Displays
