Abstract:	Applied Research Laboratories, The University of Texas at Austin (ARL:UTl. developed a hardware interface, the ARL:UT/Rockwell Collins Interface ‘Unit (ARCIU). This interface unit allows data collection from, and (limited) control of, a Rockwell Collins 3S GPS receiver from anv RS-232 interfaced cornouter. The ARCIU was developed for the Naval Oceanographic Office (NAVOCEANO) as part of the Hydrographic, Satellite, Tracking, and Ranging (HYSTAR) shallow water sun/eying system. The ARCIU is a microprocessor controlled unit which attaches to the instrumentation port (IP) of the 3S to handle protocol conversion, data buffering, data sampling, and has precise time transfer capabilities. The ARCIU, although developed in support of a specific project, was designed as a generic collection/control interface for the 3S receiver. The ARCIU is capable of supporting several types of missions. This paper will address the design and operational characteristics of the ARCIU.
