摘　　要：研究初始位置、转移时间都不固定的双冲量Lambert变轨问题,提出一种能量最省的由地球低轨道进入同步静止轨道的快速定点入轨方法。该方法以两次变轨能量消耗和变轨时间为优化目标,以低轨道等待时间和转移轨道运行时间为约束条件,利用遗传算法寻优得到一条能量消耗少、定点入轨的双冲量快速转移轨道。仿真结果表明,本文方法与传统的Hohmann转移方法能量消耗接近,但轨道转移时间和冲量次数都减小,仿真结果验证了本文方法的有效性。Two-impulse Lambert orbit transfer issue with unfixed initial position and transfer time is researched in the paper. A method of fast direct fixed-point orbit transfer from low earth orbit to geostationary earth orbit is proposed in the paper. The method uses two impulse energy and transfer time as the optimization goal and the waiting time in the LEO and the geosynchronous transfer orbit time as the constraints, and obtains a fast two-impulse fixed-point transfer orbit with less energy consumption by genetic algorithm. Simulation results demonstrate that the energy consumption of this method is approximate to the Hoffman orbit transfer method, while the transfer time and impulse number are reduced. The results show the validity and feasibility of this method.
