The invention provides an area coverage control method for an offset momentum satellite, which comprises the following steps that a first momentum wheel, a second momentum wheel and a third momentum wheel are adopted to execute attitude control in an offset momentum control mode, the nominal angular momentum directions of the first momentum wheel and the second momentum wheel are in a YOZ plane of a satellite body system and are distributed on two sides of a Y axis, the included angle with the Y axis is 45 degrees; the nominal angular momentum direction of the third momentum wheel is in the Z axis and is a backup of the two V-shaped momentum wheels; and the three-axis axial magnetic torquer is used for unloading the momentum wheel.
本发明提供了一种偏置动量卫星的区域覆盖控制方法,包括:采用第一动量轮、第二动量轮和第三动量轮通过偏置动量控制方式执行姿态控制,其中第一动量轮和第二动量轮的标称角动量方向在卫星本体系的YOZ平面,分布在Y轴两侧,与Y轴夹角为45°;第三动量轮的标称角动量方向在Z轴,为两个V型动量轮的备份;而且采用三轴轴磁力矩器用于动量轮卸载。
