I remember the flying of caesium or other atomic clocks round the
world, and that folks had to invoke relativistic corrections. Were
these better than microseconds as well?
Please excuse me if I leave relativistic corrections to the late
Professor Einstein! It's not something I've ever needed to know!
Richard,
I meant the flying clocks (microseconds). Relativistic corrections are, I
understand, needed for GPS satellites, though.
Cheers,
David
