THE APPARENT INPUT AXIS MISALIGNMENT ERROR CAUSED BY ANGULAR ROTATION ABOUT THE OUTPUT AXIS OF A SINGLE-DEGREE-OF-FREEDOM, RATE-INTEGRATING-GYRO

Abstract

Results of laboratory testing of inertial grade strapdown single- degree-of-freedom gyroscopes has revealed that a deterministic error, proportional to rate squared, is generated when the gyro is subjected to angular rates about the output axis (OA). Tests further indicate that the rate error is related in some way to OA friction effects. This is evident from tests conducted on gyros where an attempt was made to reduce the OA friction coefficient by use of dithering jewel and taut wire suspension. Additional laboratory tests are being conducted in order to identify the exact source of the error.
