位于静止轨道上的广播卫星,它的天线射束呈锥形.本文用球面三角的方法,给出下面两个问题的计算方法:1.希望卫星天线射束覆盖某个指定区域,天线射束呈何锥形?2.已经设计好的天线射束它将复盖哪个区域?这个计算方法简单、有效.
A satellite located in geostationary orbit has an antenna beam in a cone shape.This paper uses the spherical trigonometry method to calculate the following two problems: 1. We hope that the satellite antenna beam covers a designated area, and the antenna beam What is the conical shape? 2. Which area does the designed antenna beam cover? This calculation method is simple and effective.
