A spacecraft has a flat antenna array having an edge and a middle portion. A reconfigurable reaction-momentum wheel is coupled to the antenna array to roll and/or pitch the antenna array in small magnitudes. The reconfigurable reaction-momentum has a reaction operating state or mode (high-torque, low momentum) and a momentum operating state or mode (low-torque, high momentum). A thruster is coupled to the antenna array to move the antenna array.

Momentum wheels and reaction wheels for objects in space

A closed-loop motion monitoring and control system for structural mode control in a large, flexible space structure. The system uses combined sensor data to detect low-magnitude, low-frequency motion, estimate structure deformation constants, and damp structural vibrations with electromagnetic torque application.
