Abstract : In its primary mode of operation the 60-ft X-band antenna at NRL's Microwave Space Research Facility is positioned by means of a digital control system, the Navy Antenna Computer Tracking and Command (NACTAC) system. Both hardware design and software programming of the NACTAC system are operator oriented with respect to the manner in which requirements are defined and control is exercised. System operating procedures are described in detail. They include computer startup, loading of the NACTAC system program, computer-operator dialogues for entering NACTAC source data, operator-designated selections available from the main control console, NACTAC diagnostics, data card formats, and computer shutdown procedures.
