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.
Aimed at the simulation and verification of the spacecraft near-distance guidance trajectory planning, this paper develops a joint simulation system based on Visual C ++, VegaPrime and Matlab.First, the mathematical model is established.And then, the mathematical model is optimized by Matlab , And get the information such as the position, velocity and so on when the spacecraft is maneuvering closely.Multi-satellite Creator software is used to establish the model of the satellite and other objects, and the scene simulation is done by using Vega Prime.Afterwards, the system integration is done by Visual C ++, Combined with the simulation verification system.Finally, taking the optimal trajectory planning of continuous thrust fuel under the elliptical reference trajectory as an example, the united simulation system is verified.
