Finally the Galileo sattelites are beeing put in orbit. In about 5 years time we will have a really accurate sat-nav system

"We are aiming to provide one-metre, worldwide accuracy through Galileo's 'open' service - this is not possible today without regional or local augmentation," said Esa's Galileo project manager, Javier Benedicto.
"With the use of three signals, we will have access to centimetre accuracies, and with these you will see many more services than you have today; and European industry is working to develop those applications."
