Mathematical techniques developed for accomplishing Earth-based guidance of unmanned lunar and interplanetary spacecraft are described; orbit determination and guidance correction aspects are developed from linear perturbation techniques; expression for effect of neglected second order terms is developed; treatment of correlated noise on orbit determination data is discussed; policies for determining when to perform impulsive guidance corrections to orbit and technique for optimal guidance of powered flight trajectories.
