引言国际民航组织(ICAO)于1992年10月批准了主要基于卫星技术的全球通信(COMMUNICATIONS)、民航(NAVIGATION)、监视(SURVEILLANCE)/空中交通管理(ATM)系统方案,并进入实施阶段。CNS/ATM 的最终目标是 ATM 的安全,是一个完整的大系统,将不存在目前形式上的通信、导航、监视或其它独立系统,但该系统并非一个完全抛开现有设备、技术、模式全新的一个系统。而是保留了现有的优秀模式,引进了新的技术、概念并在不断发展完善的一个系统,同时,也是上述各种专业技术相互交叉、融合的一个系统,因此在新
INTRODUCTION ICAO approved the major satellite-based communications, NAVIGATION and SURVEILLANCE / ATM systems programs in October 1992 and entered the implementation phase. The ultimate goal of CNS / ATM is the security of ATM. It is a complete large-scale system. There will be no current forms of communication, navigation, surveillance or other independent systems. However, this system is not a complete disregard of existing equipment, technologies and modes A new system. But retains the existing excellent model, the introduction of new technologies, concepts and continuous development and improvement of a system, at the same time, is also a variety of professional and technical cross-integration of a system, so in the new
