Using passing aircraft for geolocation is not new (for example, it has been famously used for geolocating the HWNDU flag).

But I think this is the first time I've seen someone use signal analysis based on (sometimes inaudible) doppler shifts of aircraft and comparing it to simulated curves based on location, elevation data, and ADS-B aircraft data.

Nice #OSINT technique! Could be used to doxx people from phone calls, live streams, or recordings.
