针对目前航天器近距编队长期飞行中存在的HCW模型精确度不够的问题,提出了利用平均轨道根数线性微分漂移率预测J_2摄动下航天器近距编队相对运动的方法,建立了一种新的航天器近距编队轨道动力学模型.仿真结果表明,解析模型计算得到的相对运动轨道和不考虑J_2摄动影响的相对运动轨道相比,解析模型运算时间很短,精度提高约50%(10个轨道周期之后),证明了模型的有效性和快速性,适合在线运行,同时给出了解析模型的适用范围.

The precision of the HCW model that characterizes spacecrafts proximity formation long-term flying is not enough. For this problem, a new orbital dynamic model for proximity formation flying of two spacecraft formations is presented in this paper. Simulation results show that the operation time consumed by the analytical model is small and the precision is added up to 50%(10 orbital periods later) when comparing the results between this analytical model and the no J_2 model. Because of the effectiveness and the rapidness of this model, so it can be used on-line. In the end, the application range of this model is given.
