Abstract: Analysis of the Coriolis vibratory gyroscopes sensitive element dynamics in terms of the amplitude-phase variables led to the proper transfer functions of such inertial sensors, where angular rate is an input. Obtained transfer functions were simplified for the several special cases and then used to derive poles, amplitude, and phase responses of CVG. Performance of the simplified transfer functions is also analyzed and compared to the accurate numerical model of the sensitive elements dynamics. Obtained transfer functions were then used to derive static (Wiener) and adaptive (Kalman) optimal filters of stochastic sensor noise for Coriolis vibratory gyroscopes.
