Title: Nutation damper for two-axis gyroscope

Abstract: An electrical circuit interposed between the pickoffs and torquers of a two-axis gyroscope. The circuit output controls the torquers. When the pickoff signals vary at the nutation frequency, the angular accelerations produced by the torquers damp the nutation. No angular accelerations are produced when the pickoff signals are not varying and only negligible angular accelerations are produced when the pickoff signals vary at a frequency other than the nutation frequency.
