An embodiment of a gyroscope subsystem that is configured to reduce, or to eliminate, the effect of bias includes a gyroscope assembly, a calibration assembly, a determining circuit, and a bias-reducing circuit. The gyroscope assembly is configured to generate a gyroscope signal in response to a calibration angular velocity and another angular velocity about a sense axis, and the calibration assembly is configured to generate, about the sense axis, the calibration angular velocity. The determining circuit is configured to determine the other angular velocity in response to the gyroscope signal, and the bias-reducing circuit is configured to reduce a bias component of the determined other angular velocity in response to the gyroscope signal. For example, such a gyroscope subsystem can yield a value of an angular velocity having a bias component that is significantly less than the bias component of a value yielded by a conventional gyroscope subsystem.
