The solution reliability of the two-point boundary-value problem associated with the optimal attitude control of rigid spacecraft is enhanced through a combination of techniques. Major emphasis is placed upon the formulation of the best possible starting or nominal solution for the method of particular solutions. Constraint relationships among the state and costate variables are utilized. A hybrid approach which begins with the direct gradient method and ends with the indirect method of particular solutions is proposed. Test case results which indicate improved reliability are presented.
