Galileo
"The Galileo network will differ from GPS, not only in the fact that it will be a civilian-run service but also in that it will offer performance guarantees."
It may offer performance guarantees but will they be met and what will the price of failure be? I think we should be told! Best Guess = price of failure will be met by UK tax payers while people go blind, suffer Alzheimers and don't get cancer drugs!
