Abstract (en)

[origin: WO9817973A1] A gyroscope (36) includes a gyro body-portion (48, 50, 52 or 54) which is driven into vibratory primary oscillation P and, if turned about on axis X, Y or Z experiences a Coriolis force induced vibration. Matching the primary oscillation mode and the secondary modes allow one to accurately detect motion about one, two or three axis.
