Theory of Errors of a Multigimbal, Elastically Supported, Tuned Gyroscope

An elastically supported, tuned gyroscope is a complex device, but experience has shown that it can be represented by mathematical models by means of which practically all of its characteristic errors can be analyzed and predicted with good accuracy. The gyro angular transfer function, derived in [1], serves as an excellent basis of evaluation of errors due to asymmetries of the gimballing system and effects of rotor angular offsets. The gyro translational transfer function, derived in this paper, may be used in the analysis of errors caused by linear acceleration inputs.
