scope:

Existing (basic) ARTS III systems are essentially beacon tracking level systems, i.e., they process and track secondary radar (beacon) data derived from up to two ASR systems. These data are processed, tracked and displayed on a CRT in association with automatically and semiautomatically display symbology and alphanumerics. The latter provides aircraft identification, Mode C derived altitude, target velocity and/or radar beacon code readout to the operator (Air Traffic Controller). The system permits the operator to enter data and selectively display, alter or delete data consistent with operational needs. Normal primary as well as secondary radar presentations are displayed concurrently with the symbolic and alphanumeric data. The system also provides the capability of data/message interchange with ARTCC computer systems. Basic ARTS III systems are equipped with a magnetic tape subsystem used principally for loading the software program and a teletypewriter subsystem primarily used for on-line printing of system status messages.
