The underlying purpose of the investigation was to evolve a ring laser gyro design suitable for application in unaided aircraft inertial navigation systems. Significant improvement in laser gyro performance capability was the program goal, to be attained by analyzing and modifying parameters affecting gyro drift and reaction time. In addition to the analytical effort, the work scope included fabrication and testing of an experimental ring laser gyro RLG of new design. The prime effort was not directed toward developing new concepts but rather toward improving good available designs by choice of materials, circuit modifications, packaging, etc. The goal of instantaneous operation was demonstrated with a random drift of 0.015 degreehour after less than a half hour of operation.
