How fast is your airplane?

E61i_gps_airplaneI have to wonder if the cabin crew would be happy with this, but it’s still amazing that you can actually do it. Over at the E-Series blog, they used a Nokia E61i with a GPS receiver to figure out airspeed while on a flight. Makes sense that it would work since the plane had be lower than the GPS satellites; their geosynchronous orbits are around 26,600 miles out. Using the Tom-Tom software on the E61i it was easy to see that the plane was moving at 777 kmph. Sweet and now I can cross off geosynchronous from my "difficult words to use in a blog post" bingo card.
