Helicopter GPS-Data extracted from Audio-Signal on Youtube

Großartig! „Signalhacker“ Oona Räisänen hat aus der Audiospur eines Youtube-Clips (Rohfassung einer Verfolgungsjagd) die GPS-Koordinaten des Helikopters extrahiert.

These are the full lat/lon pairs of coordinates (39° 3.86′ N, 94° 34.20′ W). Nucomm says the system enables viewing the helicopter "on a moving map system". Also, it could enable the receiving antenna to be locked onto the helicopter's position, to allow uninterrupted video downlink.
