卫星通信,这是大家熟知的现代化的通信工具,但由于接收信号极为微弱,需要庞大的天线设备,造价昂贵,限制了广泛的使用。最近美国加利福尼亚州赤道通信公司新设计的一种通信卫星微型地面站,造价仅为5000美元左右,已在纽约州Niagara Mohawk电力公司用作大而积多点的数据传输网,并将进一步研究试制更新产品,这是卫星通信技术的重大发展。
Satellite communications, which are well-known modern communications tools, are cost prohibitive due to the extremely weak received signals and the need for bulky antenna equipment. Recently a new communications satellite miniature ground station designed by Equator Communications of California State of the United States costs only about US $ 5,000 and has been used by Niagara Mohawk Power Company in New York as a large and multi-point data transmission network and will further study the trial production Update the product, which is a major development of satellite communications technology.
