| 集群航天器是通过无线连接方式构成的虚拟航天器系统，考虑J2摄动下其在太阳同步轨道的空间圆形编队设计，对满足其模块间能量传输、数据交互的需要和应用需求具有重要意义．基于主、从模块平均轨道要素差建立了相对运动模型，并给出了空间圆形编队的详细设计步骤；在零J2摄动条件不再适用时，通过定量分析J2摄动对该编队构形的影响，提出了相应的修正公式；将模块修正后的平均轨道要素转换为初始时刻密切轨道要素确定了初始编队构形．采用无奇点的新四元数轨道要素进行J2摄动分析，仿真结果验证了设计方法的有效性． |
| 英文摘要: |
| Fractionated spacecraft is a virtual spacecraft system which is constituted by wireless connection. The space circular formation configuration design as the chief module at the sun-synchronous orbit for J2 perturbation, has great significance of meeting the needs of energy transfer and data exchange accurately between the modules, and its application requirements. To begin with, relative motion model is established through the difference of mean orbital elements between deputy module and chief module, and the design steps of the space circular formation configuration are given. The J2 invariant perturbation conditions are no longer applied, so the revised formula is proposed through the quantitative analysis of J2 perturbation. The initial formation configuration is determined by converting the revised mean orbital elements to the osculating orbital elements at the initial time. The nonsingular novel quaternion orbital elements are used to analyze J2 perturbation, and the efficacy of the design method is demonstrated by the results of simulations. |
