Title: Three axis gyro

Abstract: In a gyroscope including a rotor spinning about a spin axis, the rotor gimballed about two mutually perpendicular axes and including cross coupled closed loops operative on the two mutually perpendicular axes so as to be able to detect rates about said two axes, a feedback loop is provided to cause the gyroscope spin axis to nutate in a cone about its nominal, blind, spin axis at a controlled amplitude and at a frequency which is at least close to the natural nutation frequency of the gyro and the nutation detected and changes in the nutation amplitude or frequency used as a measure of the rate about the blind axis.
