Study of Rapid Design Method for Earth-to-Mars Transfer Trajectory

摘要

Based on the overlapped-conic targeting method, a rapid design method for mars satellite transfer trajectories is presented. This method is a pure algebraic algorithm without any numerical integration, which has an advantage of rapidity and high accuracy and is suitable for the preliminary design of earth-to-mars transfer trajectories. According to the effects of earth oblateness on the earth-to-mars transfer trajectory, this paper presents a method of correcting the earth oblateness. The result proves that it can greatly improve the accuracy of the rapid design method mentioned above.
