Аннотация: Some results of the investigation related to design of a precision stabilization system for a high-orbit space telescope with flexible elements, whose contribution to the inertia tensor reaches 80%, are discussed. The stabilization system represents a combined control system with open and closed control loops, in which the actuators are represented by a gyro system having four control moment gyros and four reactive wheels. The open loop control is employed to orient the telescope's optical axis to the attraction domain in accordance with the feedback control law. The closed loop is used both in the slewing mode for stabilizing programmed motions and in the basic (fine pointing) mode.
