Many future NASA programs require very high accurate pointing stability. These pointing requirements are well beyond anything attemped to date. This paper suggests a control system which has the capability of meeting these requirements. An optimal control law for the suggested system is specified. However, since no direct method of solution is known for this complicated system, a computation technique...
