Analysis and description of automatic (onboard) nutation control for unstable spin-stabilized spacecraft having unequal transverse moments of inertia larger than spin inertia; basic system consists of accelerometer for sensing nutation and signal conditioning unit (filter, amplifier, and switch) for providing power to thruster system which may or may not be part of normal spacecraft equipment thruster imparts transverse axis torque pulses appropriately phased to reduce or remove nutation which, without control, would increase without reasonable limit; analysis derives equations and relationships necessary for defining system requirements and for establishing basic performance requirements of major components.
