正如人们所说:先进的卫星通信使得世界变小,而先进的电子技术使得卫星通信终端变小。军用卫星通信终端的小型化问题倍受各国军方关注。过去,像AN/FSC-78这样高性能的地面站需要安装18.2米直径的大型碟状抛物面天线,在战术应用时显然太笨重了。近几年,卫星通信终端的小型化取得了重大进展,车载天线的直径从5米降到2米,便携式无线的直径降到1.5米,有的甚至小于1米。美军的“全球移动”(GloMo)计划
As people have said: advanced satellite communications make the world smaller, while advanced electronic technologies make satellite communications terminals smaller. The miniaturization of military satellite communications terminals has drawn much attention from various countries. In the past, high-performance ground stations such as the AN / FSC-78 needed to have a large dish-shaped parabola antenna of 18.2 meters in diameter, apparently too bulky for tactical applications. In recent years, significant progress has been made in miniaturizing satellite communication terminals. The diameter of car antennas has dropped from 5 meters to 2 meters. The diameter of portable radios has dropped to 1.5 meters and some even to less than 1 meter. US Army’s GloMo program
