摘　　要：以航天器近距离导引轨迹规划仿真验证为目标,对基于Visual C++,VegaPrime和Matlab的联合仿真系统进行开发研究.首先,建立了数学模型.然后,利用Matlab对所建立的数学模型进行优化求解,得到追踪航天器近距离机动时的位置、速度等信息.并通过Multigen Creator软件建立卫星等对象的模型,使用Vega Prime进行视景仿真.之后,采用Visual C++进行系统集成,建立基于三者相结合的仿真验证系统.最后,以椭圆参考轨道下近距离交会的连续推力式燃料最优轨迹规划为例,验证了该联合仿真系统.Aiming at simulating and verifying trajectory planning for spacecraft proximity guidance,a combined simulation system based on Visual C＋＋,Vega Prime and Matlab was developed.The mathematical model of the problem was presented.Then the model was solved and optimized using Matlab,and the position and velocity as well as other information of the chaser spacecraft doing proximity maneuver were obtained.The models of satellites and other objects were built using Multigen Creator software,and Vega Prime was used for visual simulation.After that,system integration was constructed via Visual C＋＋,and the simulation and verification system based on Visual C＋＋,Vega Prime and Matlab was built.The verification of this combined system was discussed using a test case that the fuel-optimal trajectory based on continuous thrust was planned for proximity rendezvous for elliptic reference orbit.
