    摘要： Inertial measurement system and method in which a gyroscope is periodically dithered about an axis perpendicular to its input axis, a signal from the gyroscope is delayed to provide a delayed signal which lags the gyroscope signal by one-half of the dithering period, and the delayed signal and the signal from the gyroscope are combined to provide an output signal from which the bias has been cancelled.
