Airport surface collision warning system implementation

The Airport Movement Area Study System (AMASS) is a ground traffic control advisory system. It tracks aircraft and other surface targets using data from two available sensors, i.e., the airport surface radar, and the long range surveillance radar. The system stores an adaptive database which defines the airport geography and traffic rules. AMASS algorithms use the airport configuration database and aircraft track files to test for nearly one thousand hazards. AMASS issues audible warnings, and displays the location of the aircraft involved on existing monitors. System operation, technology, and future enhancements are described. Preproduction system testing and validation at San Francisco International Airport is discussed.
