在中国通信发展的历程中,卫星通信以其特有的技术优势,从无到有,从小到大,显示出了极强的生命力。从２０世纪７０年代初开始,中国通过租用印度洋和太平洋上空的国际通信卫星信道与世界上多个国家和地区开通了国际直达电路,标志了中国卫星通信发展开始起步。 In the course of the development of China’s communications, satellite communications show its strong vitality from scratch, from small to large, with its unique technological advantages. Since the early 1970s, China has opened up international direct-current circuits with many countries and regions in the world by renting international communications satellite channels over the Indian Ocean and the Pacific Ocean, marking the beginning of the development of China’s satellite communications.
