摘　　要：研究了行星际轨道的基本设计参数和设计方法。首先介绍了Lambert问题及其对基本设计参数的求解，然后利用Lambert问题解生成的PCP图搜索了全局最优的2009～2010年发射窗口，并利用卫星软件工具包（STK）模拟了萤火一号（YH-1）在复杂力模型下主要飞行轨道的全过程。计算和仿真结果表明，Lambert问题解与STK相结合，可以有效地建立行星际飞行的复杂设计轨道。Basic design method involved with some key parameters was investigated for interplanetary missions. The coded solution to Lambert＇s problem could be easily implemented to do the rough design studies, as well as to quickly produce Pork Chop Plots to analyze large windows of trajectory options. With the PCP of the Earth-Mars 2009-2010 opportunity, some specific design parameters were adopted from the PCP and then were used as a starting point for simulation and further analysis with STK＇ s software. It was shown that combing Lambert＇ s problem and STK was a high-efficient and reliable method to construct interplanetary orbit.
