摘要
采用单轴双帆板供电和单框架控制力矩陀螺(SGCMG)作为执行机构的倾斜轨道空间站,当太阳方向与轨道面夹角较大时,帆板的光照条件不易保证,为此本文针对这种类型的空间站设计了一种姿态定向模式以保证帆板的光照条件,并通过在阴影区姿态机动,利用重力梯度力矩对SGCMG进行卸载。仿真结果表明,该姿态定向模式满足太阳帆板的光照条件,重力梯度力矩卸载方法保证了SGCMG中的角动量不超出给定的范围。
Since a space station operates usually in inclined circular orbit, when the angle between sun light and the plane of orbit is large, it is difficult to guarantee illumination condition of its solar array. This paper proposes an attitude pointing mode to satisfy the illumination condition of the space station with two single-axis solar arrays, and uses the gravity gradient torque dumping maneuvers to unload the accumulated momentum in SGCMG.
