As sailors in the 17th century learned the hard way, having an accurate clock for navigation is pointless if it's too delicate to carry aboard ship and the and the same goes for the super accurate optical clocks being developed for future GPS satellites. Now an optical clock built by a team led by Matthias Lezius of Menlo Systems not only has the potential to one day produce centimeter-level GPS location fixing, but is capable of operating in a zero-gravity environment.
