ABSTRACT:
A gyro platform assembly for determining the coning rate of a spinning and oning vehicle. A rotatable gimbal is attached to the vehicle such that the axis of rotation of the gimbal is in line with a spin axis of the vehicle. A rotatable platform, that supports three gyros, is attached to the gimbal. An axis of rotation of the platform is perpendicular to the axis of rotation of the gimbal. Each gyro has a rotation sensing axis, the sensing axes being mutually orthogonal, one such sensing axis being placed in line with the spin axis of the vehicle. A sensing axis, that is orthogonal to the spin axis of the vehicle, senses a coning rate of the vehicle. The output of the sensing axis is processed by a computer. The computer outputs a value equal to a sine of the coning rate of the vehicle.
