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 designed to support Automatic Dependent Surveillance – Broadcast (ADS-B). The FAA has deployed ASDE-X at 36 of the busiest airports in the United States.
