What is it about?
Our research looks into GPS signal issues in aviation, focusing on GPS jamming and spoofing. By analyzing a vast amount of flight information, we found a link between these GPS problems and official navigation warnings (NOTAMs). Our findings suggest that areas with more flight traffic experience higher GPS issues and that these issues tend to last longer where NOTAM warnings are in effect. Additionally, we discovered that GPS spoofing attempts are more common in areas with warnings about navigation interference. This highlights the importance of NOTAMs in alerting pilots to potential GPS-related problems during flights.

Why is it important?
Our findings show that GPS anomalies in aviation are strongly linked to areas of high traffic and navigation warnings, and can even persist where signals are expected to be reliable. By combining billions of ADS-B messages with NOTAM data, we reveal a timely and large-scale pattern of GPS gaps and deviations relevant to flight safety. This evidence supports using NOTAMs as an important tool to help crews anticipate and manage GPS risks in real time.
Perspectives
Writing this paper was particularly rewarding because it brought together vast, real-world datasets and practical operational insights - something I’ve been passionate about since my early work in aviation safety. Diving into billions of ADS-B messages and correlating them with NOTAMs reminded me how data science can directly inform and improve everyday flight operations. I’m excited by the prospect that our findings could prompt more proactive use of NOTAMs to anticipate GPS issues, potentially enhancing safety and efficiency in the skies
