METHOD FOR DETERMINING THE ROTATION SPEED OF AN AXISYMMETRIC VIBRATING SENSOR AND INERTIAL DEVICE FOR IMPLEMENTING SAID METHOD

摘要

The method of determining the speed of rotation of an axially symmetrical vibrating sensor of order 2. The method includes: performing a first evaluation of the speed of rotation while a vibration generated by the vibrating sensor lies in a first position relative to electrodes generating the vibration; applying a precession command so that the vibration comes successively into positions that are offset by 45°, 90°, and 135° relative to the first position; performing evaluations of the speed of rotation while the vibration lies in the offset positions; and taking a mean of the evaluations of the speed of rotation in the various positions of the vibration.
