椭圆参考轨道的卫星编队队形设计比圆参考轨道要困难得多,有时很难找到符合队形要求的初始条件。基于L aw den方程,给出了利用遗传算法设计椭圆参考轨道情形下的星下点圆形编队设计方法。由于参考轨道为大偏心率椭圆轨道时不存在圆形星下点队形,只讨论了参考轨道为小偏心率椭圆的情形。与对圆参考轨道的C-W方程初始条件进行修正的方法相比,该方法有更高的设计精度。最后使用脉冲推力模型求解了椭圆参考轨道编队的能量最省队形重构的轨迹规划问题。结果表明,遗传算法可以很好地应用于小偏心率参考轨道编队的队形和重构轨迹设计中。
The satellite formation formation design of the elliptical reference orbit is much more difficult than the circular reference orbit, and sometimes it is difficult to find the initial conditions that match the formation requirements. Based on the L aw den equation, a design method of circular formation for the star point under the circumstance of designing elliptical reference orbit by genetic algorithm is given. Since there is no circular star point formation when the reference orbit is a large eccentricity elliptical orbit, only the case where the reference orbit is a small eccentricity ellipsoid is discussed. Compared with the method of correcting the initial conditions of the C-W equation of a circular reference track, the method has higher design accuracy. Finally, the impulsive thrust model is used to solve the trajectory planning problem of the most formation-shaped reconfiguration of energy for elliptical reference orbital formation. The results show that the genetic algorithm can be well applied to the formation and reconstruction trajectory of small eccentricity reference orbital formation.
