摘　　要：研究了空间平台发射追踪器的相关技术和组合机动路径规划策略。首先对空间发射方式、发射窗口和发射初始姿态需求进行了系统分析,选择了合理的发射方式,提出了发射方案设计策略。针对空间平台发射追踪器实现与目标远程交会的组合机动问题,进行了基于投放发射的空间交会任务分析。建立了非线性多冲量推进最优变轨数学模型,以及基于空间发射的多约束多参数组合机动路径规划模型。设计了遗传算法+序列二次规划串行混合求解策略进行求解,并对发射方案和参数选择的必要性进行了仿真分析。仿真结果表明,本方法能够有效实现基于空间发射的远程交会任务设计及组合机动路径规划。研究结果为空间发射任务和组合机动路径规划提供了有价值的参考。Launching technology that space platform releases the chaser,together with trajectory planning of combined maneuver,is studied in this paper. Based on analysis on launch mode,launch window and initial launch attitude requirement,drop launch is chosen,and launch scheme is proposed as well. Aiming at the representative combined maneuver which is a long-distance rendezvous based on space launch technology,mission analysis is carried out. Nonlinear mathematical model for optimal multiple-impulsive rendezvous is given,and trajectory planning model subject to constraints is established for combined maneuver. A serial hybrid algorithm combining GA with SQP is designed. Moreover,the necessity analysis and simulation is carried out for launch scheme and parameters. Simulation results indicate that the analysis and strategies can availably implement the space launch mission design and trajectory planning for combined maneuver. Some results are valuable for applications on space operations.
