Abstrakt: This paper proposes a new guidance law for a lunar landing module. The guidance law is derived from the minimum fuel path solved by the optimal control theory. The attitude angle of a landing module is given to minimize the fuel consumption without iterative calculation. The information of thruster, thrust and specific impulse, is not necessary and only the data from an inertial measurement unit is used. The numerical results show that the guidance law has a high robustness of not only tenninal constraints but also optimality of fuel consumption.
