Abstract
A control system is designed to improve the pointing performance of a large Earth observation camera carried by a spacecraft. The spacecraft camera is mounted to the spacecraft thorough active truss members. The control system uses a cluster of reaction wheels together with piezoelectric struts. The improvement in the pointing performance using this dual actuator system is demonstrated through simulations.
