| Abstract: | In this paper,the precise initial guidance law based on velocity gain guidance and the state transition matrix for orbit interception were proposed.The miss distance caused by guidance method error and the effects of perturbation are compensated in this initial guidance law.The simulation results show that the precise initial guidance method is rational and efficient,and it can greatly improve the accuracy of orbit interception with an extra little fuel consuming. |
