The invention discloses a method for adjusting an earth pointing angle of a satellite, and aims at correcting an altimeter signal transmitting beam pointing deviation caused by structural deformation before and after a satellite enters an orbit through a whole satellite attitude offset method. The method comprises the following steps: designing a whole-satellite attitude maneuvering adjustment direction; analyzing and calculating an angle range of maneuvering adjustment of the whole-satellite attitude; analyzing and calculating the angle step pitch of maneuvering adjustment of the whole satellite attitude; designing a whole-satellite attitude maneuver path; executing attitude maneuver, and carrying out altimeter measurement data analysis; and enabling that the satellite flies in an offset manner according to the adjusted attitude angle. The method is suitable for satellites equipped with altimeters.

    本发明公开了一种进行卫星对地指向角度调整的方法,实现通过整星姿态偏置的方法来修正卫星入轨前后结构变形所带来的高度计信号发射波束指向偏差的目的。包括:设计整星姿态机动调整的方向;分析计算整星姿态机动调整的角度范围;分析计算整星姿态机动调整的角度步距;设计整星姿态机动的路径;执行姿态机动,进行高度计测量数据分析;卫星按照调整完的姿态角度偏置飞行。本发明所述方法适用于装备有高度计的卫星。
