A complete design of hardware-in-the-loop simulation system for the guidance and control system of the two-dimension course correction fuze is presented in this paper. Two motors are taken to simulate the movement of the correction discreteness and the projectile body according to the real roll information of the two parts, and a photoelectric encoder is used to correct the testing error of the geomagnetic module. Interaction between the onboard computer and simulation computer is controlled by the process control software, then, information needed in the simulation system can transmit successfully. By this way, accurate simulation of the brake control is obtained. Procedure of the simulation is also presented here, and experiment for a certain mortar is conducted. The experimental result shows that the simulation system can effectively test the guidance and control system of the fuze.
