Errors due to bearing vibration for dynamically tuned gyro operating as angular velocity sensor

Errors of the dynamically tuned gyro operating in the mode of angular velocity sensor caused by vibration of a ball bearing, are considered. The levels of axial and radial noise are analysed with regard to specific defects of the ball bearing manufacturing. Transfer function is determined for the gyro operating as angular velocity sensor, on its basis the gyro error estimation is obtained.
