Abstract
Nonlinear methods of high-accuracy spatial attitude control for a flexible large-scale remote-sensing spacecraft are described. The effective damping of oscillations within such a flexible structure, using gyrodines (single g imbal control moment gyroscopes) with electromagnetic suspended rotors, is also developed. Ultra-precise image motion stabilization is achieved by mov ing image compensators in an onboard optical telescope. (C) 1999 Elsevier S cience Ltd All rights reserved.
