Europe's Galileo is the world's most precise satellite navigation system, providing metre-level accuracy and very precise timing to itsfour billion users. An essential ingredient to ensure this stays the case are the atomic clocks aboard each satellite, delivering pinpoint timekeeping that is maintained to a few billionths of a second.
