休斯飞机公司和TRW国防与空间系统部各自从美国航宇局获得一百万美元研究费,研究高频通信卫星。由于现有的通信卫星频段4～6千兆赫和11～14千兆赫到九十年代初即将饱和,所以美国航宇局目前正在为此项研究工作进行投资。为了解决频段饱和问题,将
Hughes Aircraft Company and TRW Defense and Space Systems each received a one-million-dollar research grant from NASA to study high-frequency communications satellites. NASA is currently investing in the research because of the saturation of the existing communications satellite bands of 4 to 6 GHz and 11 to 14 GHz to the early 1990’s. In order to solve the band saturation problem, will
