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.

Inertial measurement system and method with sensor bias cancellation

System having one or more inertial sensors in which one or more of the sensor input axes are modulated in orientation about an axis substantially perpendicular to the input, or sensitive, axis of the sensor and, in some embodiments, by also enhancing the accuracy of such a system to provide improved signal to noise ratio and reduced sensitivity to errors in alignment of the sensor axes to the dither axes.
