摘要/Abstract

摘要：

广播式自动相关监视(ADS-B)技术具有监视精度高、刷新快、成本低、维护简单等优点,得到民航空中交通管制部门的青睐,常用于航路监视服务。ADS-B水平位置不确定度作为ADS-B的重要参数,反应了目标定位的水平精度等级。文中统计和分析DO-260版本的水平位置不确定度,验证了不同水平精度等级位置误差的正态性。基于位置误差的概率统计特性,评估了当前ADS-B运行间隔下的目标冲突和危险接近等碰撞风险,为ADS-B管制下的飞行间隔评估提供理论基础。

关键词: 自动相关监视, 水平位置不确定度, 碰撞风险, 空中交通管制

Abstract:

Automatic Dependent Surveillance Broadcast (ADS-B) technology had the advantages of high monitoring accuracy, fast refresh, low cost and simple maintenance. It was favored by civil aviation air traffic control departments and was often used in route surveillance services. As an important parameter of ADS-B, the horizontal position uncertainty of ADS-B reflected the level accuracy of target positioning. In this paper, the horizontal position uncertainty of DO-260 version was analyzed, and the correctness of position errors of different levels of horizontal accuracy was verified. Based on the probabilistic and statistical characteristics of position error, the collision risks such as target conflict and danger proximity under current ADS-B operating interval were evaluated, which provided a theoretical basis for flight interval assessment under ADS-B control.

Key words: automatic dependent surveillance, horizontal position uncertainty, collision risk, air traffic control
