Abstract : This effort is significant to the Air Force in that an angular rate sensor is being developed that will eventually result in the production of a low-cost, reliable, strapdown inertial system. The results of a ring laser techniques investigation performed by Autonetics Division of North American Rockwell Corporation are presented in this document. The objective of the contract was to demonstrate laser gyro performance suitable for strapdown guidance and navigation systems. This was accomplished with a Ring Laser Gyro (RLG) instrument design development that included a gyro configuration study, bias mechanism study, and use of the results from an RLG parameter and component function study conducted under the previous Air Force Contract, F33615-68-C-1382. Linearization electronics were also designed and constructed. Several tests were performed with the completed instrument plus linearization electronics. These tests included long-term drift and repeatability, linearity, magnetic field sensitivity, input axis alignment and stability, and temperature sensitivity. Recommended design refinements are presented for performance improvement on a prototype instrument. (Author)
