Abstract : This document presents detailed computer algorithms for programming the Automatic Traffic Advisory and Resolution Service (ATARS). A major feature of this version of the ATARS algorithms is the capability to exchange resolution advisory information via the airborne Resolution Advisory Register (RAR). This provides for coordination of resolution advisories between ATARS and airborne collision avoidance systems and between adjacent ATARS sites in the absence of ground communication lines. The ground based ATARS computers use the surveillance data from the Discrete Address Beacon System (DABS) to provide properly equipped aircraft with traffic advisories and collision resolution advisories. These advisories are discretely delivered to the aircraft via the DABS data link. The ATARS algorithms are presented in two volumes rather than one large document in order to provide the algorithms in a more manageable form.
