The best view of the Tour is from space

It is now possible to track the position and speed of each rider in the Tour de France in real-time thanks to the EGNOS European satellite positioning system, a preparatory programme for the Galileo system.

Thanks to satellites, it will be possible to know at any given time where each rider is and how he is doing in the race, whether he is in the peloton or has broken away and is out in front.
