摘　　要：深化ADS-B技术的部署与应用一直是民航局战略规划的核心要义,ADS-B技术作为空中交通管制领域的重要创新,显著提升了飞行安全性和效率。电离层异常是ADS-B技术应用的一个巨大挑战,由于ADS-B监视源信息来源于机载导航系统,当发生电离层异常时,机载导航系统中卫星信号的幅度与相位发生显著的抖动,进而影响测距源的可信度。本文主要采用模拟异常信息的方法实现了电离层异常时对ADS-B监视源信息水平方向精度和完好性的评估。Deepening the deployment and application of ADS-B technology has always been the core of the strategic planning of the Civil Aviation Administration of China.As an important innovation in the field of air traffic control,ADS-B technology has significantly improved flight safety and efficiency.Ionospheric anomalies are a huge challenge for the application of ADS-B technology.Since the ADS-B surveillance source information comes from the on-board navigation system,when there is an ionospheric anomaly,it will cause significant jitter in the amplitude and phase of the satellite signal in the on-board navigation system,which in turn affects the credibility of the ranging source.This article mainly uses the method of simulating abnormal information to achieve the evaluation of the horizontal accuracy and integrity of ADS-B surveillance source information in the presence of ionospheric anomalies.
