一、概述自动相关监视(Automatic dependent surveillance简称ADS)系统是一种为空中交通管制服务的监视系统。系统作用主要通过数据链,从飞机自动发射各种航行数据、地面接收各种数据并自动显示,实现飞行员与管制员之间信息的自动交换,大大减少使用话筒通信的次数。我们知道,空中交通管制服务的目的,一是防止航空器与航空器相撞;二是加速和维持有秩序的空中交通活动。为实现此目的,当今世界普遍采用“程序管制”和“雷达管制”的方法,来确定飞机识别标志,飞机的位置、高度、速度以及时间等数据,完成空中交通管制任务。目前,全球分为三种形式的空 First, an overview Automatic related surveillance (Automatic dependent surveillance referred to as ADS) system is a service for the air traffic control monitoring system. System role mainly through the data link, from the aircraft automatically launch a variety of navigation data, the ground to receive a variety of data and automatically display, to achieve automatic exchange of information between pilots and controllers, greatly reducing the use of microphone communication frequency. We know that the purpose of air traffic control services is to prevent aircraft from colliding with aircraft and to speed up and maintain orderly air traffic activities. In order to achieve this goal, the current “control of the world” and “radar control” methods are commonly used to determine the identification of the aircraft, the position, altitude, speed and time of the aircraft to complete air traffic control tasks. At present, the world is divided into three forms of space
