摘要
要使卫星接收天线能够正常收到卫星发射的信号,天线的方位角和仰角的准确定位至关重要。天线的方位角和仰角可以根据公式在安装调试天线以前计算出来,但是,由于卫星接收天线的大小不同,结构各异,对一副实际天线的方位角和仰角进行测量定位是一件很难做到的事情。所介绍的方位角和仰角的定位方法使用简单、有效,适用于多种结构的卫星接收天线。
Directed angle and elevated are important in receiving the signal of satellite. It can calculate according to formula before installing antenna. Because antenna is different, the fixed method is difficult. This article introduced a simple method to solve this problem which is suit to different forms satellite receiver antenna.
