Abstract:

Primary effort was devoted to the evaluation and initial operation of the single-axis, wire supported, space-vehicle simulator. A bang-bang attitude control system was implemented to aid in the evaluation of the simulator and a new draftfree enclosure was constructed to house the simulator. Two pieces of special purpose test equipment, a sun sensor and a light source, were designed and fabricated. An integrated power system, designed for the simulator, is in the process of implementation. Implementation of the attitude control system was initiated. The horizonsensing system was qualitatively evaluated, and a derived-rate controller was mechanized and operated. Author
