The Geophysical airborne Survey System GASS, developed by the Naval Ocean Research and Development Activity, is a real-time, distributed microprocessor sensor system. The Naval Oceanographic Office intends to use this system on the Project Magnet P-3 Orion aircraft to collect worldwide magnetic and hydrographic data. This report briefly discusses the mission and the history of GASS and reviews the technology advances of the last decade in the area of real-time distributed microprocessor systems. Specific topics include the goals of distributed system design, the qualitative value of distributed system design, and reliable design techniques for the hardware and software in distributed systems. This technology review provides a foundation for the GASS design. The systematic design decisions made for GASS are detailed, and the systems architecture is described. Detailed drawings and descriptions of the hardware and software for the final GASS design are also included. Recommendations are made for possible system enhancements and for areas that require further investigation.
