从1963年美国发射第一颗同步卫星以来,通信卫星的发展已经历了近二十年的历吏了。在这二十年内,随着通信卫星的广泛应用,卫星通信技术出现了长足的进展,特别是从七十年代以来,为了提高卫星的通信容量或工作能力,世界上许多国家都对多波束天线、固体器件、卫星开关/时分多址等许多先进的卫星通信技术开展了广泛的预研和试验。
Since the United States launched its first geostationary satellite in 1963, the development of communications satellites has experienced nearly two decades of history. In these two decades, with the widespread application of communication satellites, great progress has been made in satellite communication technologies. In particular, since the 1970s, many countries in the world have been concerned with the multi-beam antenna , Solid state devices, satellite switches / time division multiple access and many other advanced satellite communications technology to carry out a wide range of pre-research and testing.
