The BBC has an interesting story on the Galileo navigation satellites:

> The onboard atomic clocks that drive the satellite-navigation 
> signals on Europe's Galileo network have been failing at an alarming
> rate.
> 
> Across the 18 satellites now in orbit, nine clocks have stopped 
> operating.
> 
> Three are traditional rubidium devices; six are the more precise 
> hydrogen maser instruments that were designed to give Galileo
> superior performance to the American GPS network.
> 
> Galileo was declared up and running in December.
