发明名称 Self-calibration of scale factor for dual resonator class II coriolis vibratory gyros
摘要 <p>The method and apparatus in one embodiment may have: operating one of two resonators of a class 11 coriolis vibratory gyro in a closed loop mode and another of the two resonators in an open loop whole angle mode; sensing an angular rate by each of the two resonators; calibrating the scale factor of the closed loop resonator to yield the same integrated whole angle as measured by the open loop resonator; reversing operation of the two resonators such that the one of two resonators is operated in an open loop mode and the another of the two resonators in a closed loop whole angle mode; and alternately proceeding between open and closed loop operation of the two resonators, thereby self-calibrating scale factors respectively of the two resonators. </p>
