Abstract
A method and system for providing gyroscope bias self-calibration are described herein. The method comprises powering on one or more gyroscopes; after a predetermined first period of time, and upon determining that the one or more gyroscopes is stationary, measuring input rates of rotation during a predetermined second period of time; and determining an average rate of rotation for each gyroscope channel based upon the measured input rates of rotation during the predetermined second period of time. After determining the average rate of rotation and after the predetermined second period of time, the method further comprises commencing additional measurements by the one or more gyroscopes; determining calibrated gyroscope measurements by subtracting the average rate of rotation from each of the additional measurements; and providing, at the output of the one or more gyroscopes, the calibrated gyroscope measurements.
