Simon Willison shares an OSINT technique by Colsto that uses imperceptible airplane engine noise in video soundtracks to triangulate a video's exact geographic location. By analyzing Doppler curves and cross-referencing with ADS-B flight data, the method determines location based on aircraft speed, distance, and timing gaps between flights.
Background
ADS-B (Automatic Dependent Surveillance–Broadcast) is a surveillance technology that broadcasts aircraft position via GPS, publicly accessible through services like FlightRadar24. This technique represents a sophisticated blend of audio forensics and open-source intelligence gathering.
