摘要： The invention provides a gyroscope employing a sensitive element rotated by a hysteresis motor and which has an improved bias repeatability, the bias arising from vibration of the sensitive element imparted thereto by the hysteresis motor. An identifiable point associated with the sensitive element (9) is sensed by first sensor means (37, 38, 67, 71) and a pole vector associated with the hysteresis motor (6) is sensed directly or indirectly by second sensor means (64), the outputs of these sensor means being applied to comparator means (73) which is operable to compare the phase of the pole vector (V.sub.p) with respect to the identifiable point. Control means (76, 79) are also provided which are responsive to the output of the comparator means (73) and operable to adjust the phase of the pole vector (V.sub.p) with respect to the identifiable point to a required relationship, the gyroscope further comprising means (73), for maintaining that required relationship once established.The invention is particularly applicable to flexure-suspended free-rotor gyroscopes.
