求翻译：所谓自动对星就是将卫星天线的主波束中心对准要与之通信的卫星，建立通信信道的过程。将船只在航行时产生的摇摆分解成横摇（船只横向的摇摆）、纵摇（船只前后的摇摆）、艏摇（船只航向的变化）和升沉，在舰船移动时卫星天线跟踪系统的平台基准线会在方位、俯仰和横滚三个方向上发生偏移，船载伺服设备最重要的特性是能够隔离船只的摇摆。对于地球同步卫星来讲，只要地球站位置确定之后，调节天线的俯仰角和方位角就可以完成对星，在此基础上再调整馈源极化方向就可以使天线系统达到最佳状态。是什么意思？

So-called automatically in the star is the satellite antenna alignment of the main beam center to communicate with the satellite, the communication channel. When the ship sailing in the rocking roll exploded into the pan (Ships), lateral, longitudinal vessels rocking back and forth), the emergency,

So-called to the star is automatically the satellite antenna main beam center alignment must with it correspondence satellite, establishes the communications channel the process.Ships when navigation produces the swing decomposes the rolling (ships crosswise swing), the pitching (around ships swing)
