    • An apparatus includes an azimuth adjuster coupled between a motor and a directional antenna. Motor rotation causes the azimuth adjuster to rotate the antenna about an azimuthal axis. The motor rotation also causes an elevation adjuster to rotate, which causes a screw mechanism to modify an elevation angle by pivoting the antenna about an elevational axis. To aim the directional antenna, a body-direction vector of a movable body with the antenna attached thereto is determined. Based on an elevational relationship between the body-direction vector and a satellite-direction vector, the elevation adjuster modifies the elevation angle of the antenna by rotating the motor to achieve full-turn amounts to pivot the antenna. The azimuth adjuster modifies an azimuth angle of the antenna based on an azimuthal relationship between the body-direction vector and the satellite-direction vector by rotating the motor to achieve partial-turn amounts of the antenna.
    • 一种装置包括耦合在电动机和定向天线之间的方位调节器。 电机旋转使方位调节器绕方位轴旋转天线。 电动机旋转也导致升降调节器旋转,这导致螺旋机构通过绕天线枢转天线来改变仰角。 为了瞄准定向天线,确定了附接有天线的可移动体的身体方向向量。 基于身体方向矢量与卫星方向向量之间的高程关系,仰角调节器通过旋转电动机来改变天线的仰角,以实现全转动量以使天线枢转。 方位调整器通过旋转电动机,基于体向矢量和卫星方向矢量之间的方位角关系来改变天线的方位角,以实现天线的部分转弯量。
