MAGNETICALLY TORQUED NUTATION DAMPING Abstract A system for actively damping nutation of an earth orbiting spacecraft and/or aligning the pitch axis of a momentum bias spacecraft with some external reference includes a magnetic torquing means, which is energized with currents of appropriate polarity and magnitude to effect the necessary torque to reduce nutation by producing in the roll/yaw axis of the spacecraft a magnetic dipole for reaction with the earth's magnetic field. A roll sensor produces signals proportional to and representing the direction of the attitude error of the satellite with respect to a desired attitude. A control signal is generated a predetermined time period after the roll error exceeds a predetermined threshold. The predetermined time period is a fraction x of the nutation period tn of the satellite or x + n(tn) where n is an integer.
