Abstract
A three axis, single degree of freedom gyroscope based rate sensing platform has restraining torque developed for the platform from a feedback loop that includes electronics that decouples individual gyroscope outputs from the rate inputs that correspond to axes other than the input axis for that gyroscope and provides an enhanced frequency response. The outputs from the various gyroscopes are processed in a compensator that estimates the platform rates on independent axes using either a Kalman filter estimator or a matrix inverse of the matrix equation of motion between platform input rate and gyroscope output. High bandwidth performance is obtained by an increased stiffness and prefiltering of the gyro torque inputs.
