An inertial platform carries at least one dynamically-tuned free-rotor gyro and is mounted in a three-axis gimbal system. Accelerometers are carried on the platform with their sensitive axes aligned with the two sensitive axes of the gyro. During alignment of the platform, and while the gyro motor is being run up to speed, the output of the gyro pick-off on each axis is combined with the output of the accelerometer on the other axis and applied through a resolver to the appropriate gimbal torque motor.

Gyroscopic apparatus having three-axis inertial platform with rapid

Gyroscopic apparatus comprises a gyroscopic device having two mutually perpendicular sensitive axes. The device is suspended in a two-axis gimbal system by means of cross-spring pivots of zero stiffeners. The gimbal system is further supported by a subsidiary suspension about two horizontal axes, and the subsidiary suspension carries damping means to damp movements of the gimbal system.

Gyroscopic apparatus

A free rotor gyroscope has a gimbal supported for limited rotation about a rotatable shaft by a first flexure suspension and a rotor attached to the gimbal by a second flexure suspension. Pickoff means rotate with the gimbal and detect its movements about its axis of suspension.
