随着社会的不断进步和科学技术的发展,人类对电信的要求越来越迫切,形式也越来越多样化。从通信技术和电子技术近一个世纪的飞速发展来看,以最初的近距离有线电话和人工莫尔斯无线电报开始,现已进入到高级智能终端和巨型计算机,以及光纤、卫星传输和文字、图像等的应用。作为当前先进的运输行业,民用航空是先进的科学技术成果应用处于先列的行业,而航空电信则是保证民用航空飞行安全和正常、高效的最重要的基础 With the continuous progress of society and the development of science and technology, human beings have become more and more urgent on the requirements of telecommunications and their forms have become more diversified. Starting from the rapid development of communications technology and electronic technology in nearly a century, with the initial launch of close-range landline telephones and manual Morse radios, access to advanced smart terminals and supercomputers as well as optical fiber, satellite transmission and text, Image and other applications. As the most advanced transportation industry, civil aviation is the forerunner in advanced science and technology achievement applications, while aeronautical telecommunications is the most important basis for ensuring the safety and normality and efficiency of civil aviation flight
