GPS tracking commercial flight / Google Earth
I tracked my trip from Helsinki to Paris through my cell phone GPS and surprisingly the batteries lasted enough! (Note: cell phone networks were disabled -flight mode- ensuring a longer battery life… and the full respect of the rules during takeoff and landing
Time, speed, altitude and distance can be clearly seen: liftoff by 215km/h, cruise at 800-900km/h, long approach at 300-400km/h, landing by 240km/h – of course we talk about ground speed here. Cruise altitude (10km) was not kept that long after all. Needless to say, satellite fix is perfect (up to 12 satellites acquired at some point) – but only because I was next to the window… The whole trip coordinates being recorded, a quick view from Google Earth is given at the end of the video.
