PROGRAMING, INTEGRATION AND CHECKOUT OF THE ADVANCED RADAR TRAFFIC CONTROL SYSTEM.

The Advanced Radar Traffic Control System, installed in the airport terminal building in Atlanta, Georgia, provides terminal area controllers with bright display of symbolic and alphanumeric data relative to controller initiated tracks and automatically maintains continuous association between this data and beacon and radar video by means of digital tracking techniques. The system consists of a digital computational subsystem, a beacon subsystem, and two display subsystems. The major functional elements of the operational computer program are tracking, processing of controller inserted data and requests, and preparation of property formatted messages for display. The tracking function is a multi-state alpha, beta, straight-line tracking with logical turn detection. The availability of the system's general purpose digital computers made possible an approach to equipment system integration which was primarily based upon a sequence of specially designed programed tests. System checkout was achieved through execution of a sequence of tests designed to methodically verify prescribed system operation. Special test and data extraction programs were prepared for and employed in system checkout.
