The invention provides a Y-shaped formation configuration and reconstruction method for low-orbit satellites, and the method comprises the following steps: 1, taking a satellite as a main satellite, and designing the orbit parameters of the satellite according to a task demand; 2, the other satellites except the main satellite serve as auxiliary satellites, the auxiliary satellites take the main satellite as the middle reference position of the formation, the orbit parameters of all the auxiliary satellites are designed according to the orbit parameters of the main satellite, and all the auxiliary satellites and the main satellite form a Y-shaped formation in the orbit coordinate system XOY plane of the main satellite; 3, when all the auxiliary satellites normally operate in orbit, formation maintenance control is carried out on all the auxiliary satellites; and 4, when one auxiliary satellite in the formation fails, reconstructing the Y-shaped formation configuration through the movement of the remaining auxiliary satellites on the same side. Through the Y satellite formation configuration of the low-orbit satellites, the engineering requirement of a passive microwave load for the size of a large-aperture equivalent antenna can be effectively met, so that ground high-resolution detection is realized.
本发明提供了一种低轨卫星的Y形编队构型与重构方法,包括如下步骤:步骤1:将一颗卫星作为主星,根据任务需求设计其轨道参数;步骤2:将除主星之外的其余卫星作为辅星,辅星以主星为编队的中间基准位置,根据主星的轨道参数设计各个辅星的轨道参数,使各个辅星与主星在主星的轨道坐标系XOY面内形成Y形编队;步骤3:各个辅星在轨正常运行时,对各个辅星进行编队维持控制;步骤4:当编队中的一颗辅星失效时,通过同边剩余辅星的移动进行Y形编队构型的重构。本发明通过低轨卫星的Y星编队构型,能够有效解决被动微波载荷对于大口径等效天线尺寸的工程需求,从而实现地面高分辨率探测。
