利用激光进行卫星─地面通讯采用红外激光能在空间建立信息“桥”，每根光束每秒钟可在卫星间传送十亿比特信息，而目前数字电视卫星上采用的最快无线电系统每秒只能传送２０００多万比特信息。ＴｈｅｒｍｏＴｒｅｘ公司研制的新系统名为Ｌａｓｅｒｃｏｍ。传统系统传递信...
Using lasers for satellite-to-ground communications Infrared lasers establish a “bridge” of information in space, with each beam transmitting one billion bits of information per second between satellites, and the fastest radio systems currently used on digital television satellites Can send more than 20 million bit information. The new system developed by ThermoTrex is called Lasercom. Traditional system delivery letter ...
