自动相关监视广播（ADS-B）使用GNSS和其他传感器向空中交通管制员（ATC）和其他空域用户提供飞机位置。该项目力求利用ADS-B信息快速检测和定位干扰事件，以便为依赖全球导航卫星系统的业务提供更好的保护和态势感知。该项目首先描述了已知GNSS干扰事件对ADS-B输出的影响。然后，我们利用这些观察到的行为，以确定在其他位置的可疑干扰事件。本文使用公开的ADS-B传输记录进行分析。我们试图确定的事件是基于飞行员报告的中断GNSS服务的飞机接近旧金山弗朗西斯科海湾地区机场。进近程序可能更有可能遇到干扰，这是由于更接近地面，因此也更接近潜在的射频干扰（RFI）源。此外，这些程序具有最严格的安全要求。
Automatic Dependent Surveillance Broadcast (ADS-B) uses GNSS and other sensors to provide aircraft positions to air traffic controller (ATC) and other airspace users. This project seeks to use ADS-B messages to rapidly detect and localize interference events allowing for better protection and situational awareness for operations that rely on GNSS being available. This project first characterizes the effects of known GNSS interference events on ADS-B outputs. We then utilize these observed behaviors to identify suspected interference events at other locations. This paper performs this analysis using publicly available records of ADS-B transmissions. The events that we sought to identify were based on pilot reports of interrupted GNSS service to aircraft on approach to a San Francisco bay area airport. Approach procedures may be more likely to encounter interference due to the closer proximity to the ground and therefore to potential radiofrequency interference (RFI) sources. Further, these procedures have the most stringent safety requirements.
