Re: Big Outage
The problem isn't the clock. It's Einstein, and the way that mass is not evenly distributed throughout the Earth. American GPS clocks have to be reset every day. Because they fly over the surface of the earth, and the uneven nature of mass distribution affects the special- and general-relativistic slowing of the on-board clocks. It's just not predictable, no matter how well Einstein's theories have been confirmed. Without a reset daily, GPS'es go out, way out.
