This paper considers a numerical method for optimal control problems which are solved by using a mathematical programming formulation. The sensitivity differential equations are obtained to calculate the derivative information of the objective and constraint functions. Numerical examples of the accent trajectory problem of a spaceplane compare the proposed method with the conventional method which calculates derivatives using finite difference approximation. The results demonstrate the improvement of accuracy and computational efficiency of the present method.
