GPS is a modern miracle. Using SPACESHIPS and RELATIVITY you can locate yourself anywhere on the planet.
Fun fact! Your GPS won’t work if you’re above 18Km or going faster than 500 metres per second. Just in case you’re a Soviet Guided Missile.
But if you’re on a regular international flight, you should be just fine! Here are some screenshots I took using the open source GPS Test for Android.
Top tips: make sure you get a GPS lock and update your A-GPS data. It’s also worth getting as close to a window as possible in order to see the sky without the metal shell of the aeroplane blocking you.
The sky view is particularly beautiful.
I also found a page on British Airways’ inflight WiFi which showed what the plane itself was reporting.
My cheap phone and the multi-million pound plane disagree slightly on speed and height. But not by much!
I was also able to take these geo-tagged photos of Australia from the plane.
So, next time you’re on an international flight, take a peek at the sky!
