ABSTRACT:
A gyroscope system comprises a dual-axis rate gyroscope (1) including angle pick-offs and rotor torque applying device (5), and a control circuit (3) arranged to supply a control signal to the rotor torque applying device (5) in accordance with the output angle sensed by the angle pick-offs. The system further comprises an angular acceleration sensor (2) which is independent of the dual-axis rate gyroscope and is arranged to output a signal to the control circuit (3). The signal modifies in accordance with the sensed angular acceleration the control signal supplied to the torque applying device (5). Preferably the angular acceleration sensor (2) forms part of a guidance system independent of the dual-axis rate gyroscope (1).
