摘　　要：电磁航天器编队飞行能有效降低发射成本并延长编队在轨寿命,具有广阔的发展前景。针对其强非线性和姿轨耦合的特点,采用STK软件对电磁航天器编队飞行进行仿真研究。首先对电磁航天器编队飞行基本原理进行分析,给出了轨道姿态动力学模型及解耦控制方案。然后设计了仿真系统的结构框架,解决了电磁航天器三维建模、轨道和姿态数据转换、可视化实现等关键技术,还讨论了STK接口规范。最后采用搭建的仿真系统对电磁航天器编队重构进行了仿真研究。仿真结果表明,电磁航天器编队控制效果良好,仿真系统能够满足电磁航天器编队飞行仿真研究的需要,对其它类型航天器编队仿真研究具有一定的指导意义。Electromagnetic spacecraft formation is a hopeful technology to decrease launch costs and extend life- times of space missions. In consideration of its complexity, nonlinearity and coupling of orbit and attitude motions, simulation research of electromagnetic spacecraft formation was investigated based on STK. Firstly, basic principles of electromagnetic spacecraft formation, including dynamic models and decoupling strategies, were analyzed. Then the framework of the simulation system was designed. 3D modeling, orbit and attitude data conversion, and visualization technologies were investigated. In addition, STK program interface was discussed. Reconfigurations of electromagnetic spacecraft formation were analyzed using the simulation system. Results show the feasibility of the control laws and the simulation system. The proposed simulation system has a guiding significance to other non-contract spacecraft formation flying simulations.
