Abstract:Through the analysis on kinematical constraint characters of the launch window for Earth-to-Moon transfer trajectories based on the high elliptical parking orbit, laws of kinematical constraint influence on the launch window are given, and launch opportunities of the lunar probe and the probability to add the launch window are verified. According to the kinematical constraint characters of the launch window, a fast design method for the Earth-to-Moon transfer trajectory based on the high elliptical parking orbit is provided. The simulation results show that the analysis on kinematical constraint characters of the launch window for Earth-to-Moon transfer trajectories based on the high elliptical parking orbit is correct and the design method for transfer trajectory is effective.
