随着卫星通信和广播的迅猛发展,地球同步轨道(以下简称同步轨道)上的卫星日益增多,愈来愈拥挤,据不完全统计,同步轨道上的卫星已超过100颗以上。导致了国际上同步轨道定点位置的争夺也愈来愈激烈,颇有同步轨道资源危机之感。如何在赤道上空放置更多的卫星,来解决空间轨道资源不足的问题,人们都在积极探索和寻求新的途径,来提高轨道和频谱的有效利用。除采用空间波束复用、极化复用频率
With the rapid development of satellite communications and broadcasting, the number of satellites on the geostationary orbit (hereinafter referred to as the geostationary orbit) is increasing and becoming more and more crowded. According to incomplete statistics, more than 100 satellites are in orbit. This has led to more and more fierce competition for the fixed-satellite position on the international arena, which is quite a sense of crisis of the synchronous orbit resource. How to place more satellites over the equator to solve the problem of insufficient space orbit resources, people are actively exploring and seeking new ways to improve the effective utilization of orbit and spectrum. In addition to the use of spatial beam multiplexing, polarization multiplexing frequency
