Abstract:

In Newtonian gyros, the bearings have been identified as a first order source of error. Over the years, a significant amount of research has been devoted to improving the quality of different type contact bearings. In conjunction with task of improving the bearings, a similar effort has involved identifying the bearing effects on gyro performance. The thrust in this report involves two similar types of measurements of gyro vibrations to enable detecting faulty bearings or establish a signature of gyro performance. A gyro wheel from a precise instrument application was selected for this study because of the very high quality performance required in the parent system. Author
