The trajectory numerical computation was the significant method of trajectory characteristics research. In this paper, the ballistic characteristics of trajectory correction rocket were analyzed by using ballistic theory, and the modular modeling method of trajectory correction rocket was studied by using Matlab/Simulink platform. Based on the basic modeling scheme of the function module, the modeling scheme was established, which was based on the measurement of projectile motion, navigation parameters and quidance control, and the actual modeling results were given. Finally, the initial conditions of the simulation were set up and the trajectory model was used for simulation. The results showed that the model could be well correspond with the actual rocket trajectory characteristics and the flight law. The model was verified to be reasonable and feasible.
