Keeping Perfect Time

The vibration of an atom is nature’s steadiest timekeeper; today’s atomic clocks underpin GPS, communications, and electronics worldwide. “But we and other scientists are constantl...

The Stratum-0 Atomic Clock

John Sloan (Chip Overclock) decided to move from a Raspberry Pi 3 and GPS-based clock to the accuracy of an atomic clock. Atomic clocks are not clocks in the sense of telling the t...

Fifteen years young – Rubidium Fountains continue service to the Navy’s Master Clock

WASHINGTON, D.C. – As of March 2026, the rubidium fountain clocks have met the benchmark of 15 years of continuous operation as part of the U.S. Naval Observatory’s Master Clock en...

Chinese crystal ‘paves way’ for GPS-free thorium clock navigation
