Abstract : This report presents the studies and investigations performed to determine the feasibility of and the techniques and instrumentation necessary for employing gyroscopic principles in a small, rugged instrument which can be used by Army reconnaissance and observational troops to determine azimuth to visible landmarks or other appropriate references for obtaining directional orientation. This report reviews the Phase I program, documents the Phase II technical activities and presents the overall program conclusions and recommendations. The design, fabrication and test of a laboratory model vortex-centered spinning-sphere gyro was conducted, along with a theoretical investigation of the hydrodynamic equations of motion. It was established that a fluid, vortex-centered gyro of a size and weight to meet this requirement would have a coupling time constant which was too short for north-seeking applications. A miniature, gas bearing suspended spinning-sphere gyro design was formulated which yielded an ideal solution for this north-seeking application. This basic inertial sensor was integrated with the various other subsystems to yield an overall design configuration which offers a very attractive mechanization technique for this application. The feasibility of the instrument was firmly established and it is recommended that a hardware fabrication and test program be implemented. (Author)
