Guidance and Control of a Land-survey Spacecraft with a Smooth Conjugation of Boundary Conditions

Yevgeny Somov, Sergey Butyrin, Sergey Somov
New statement of the optimization problem by the land-survey spacecraft (SC) rotation maneuver with the general boundary conditions is considered. Methods for exact numeric and approximate analytic solution of the stated problem, and also some results on synthesis of the SC guidance laws with a smooth conjugation of boundary conditions are presented. Methods and results on the SC robust width-pulse and digital attitude control are also represented.
