ADS-B
Automatic Dependent Surveillance–Broadcast, an aviation surveillance technology in which aircraft automatically broadcast their position, altitude, speed, and other flight data via radio signals. It constitutes a core data source for modern flight tracking systems.

Combining ADS-B trajectory data (including the aircraft's position, speed, altitude and timestamps), the observer's geometric position relative to the aircraft's trajectory can be inferred.
Global flight tracking data (such as ADS-B) is public and records the real-time position, altitude and speed of every aircraft.
Colsto said he is not the first person to think of using airplane noise, but no one had previously systematically demonstrated how to combine it with ADS-B data for precise localization.
This technique requires isolating airplane noise from the video's audio track, extracting the Doppler curve and matching it against ADS-B data, demanding audio processing knowledge and programming or specialized software skills.
A large number of volunteers upload received ADS-B data to platforms such as Flightradar24 and OpenSky Network, forming a public flight tracking database covering the globe.
By cross-matching the Doppler curve extracted from the video against ADS-B data, when the data for multiple aircraft match simultaneously, the filmer's location can be pinned down to a very small area.

ADS-B is the standard broadcast positioning protocol in modern aviation, with aircraft actively broadcasting data frames containing GPS coordinates, altitude, and speed to the outside approximately every 0.5 seconds.
