Real-time precise point positioning (RT-PPP) depends on accurate satellite clock products, but phase jumps, frequency jumps and complex clock anomalies can destabilize network clock estimation.

Markus Lutz is CTO and Founder of SiTime Corporation. He is a MEMS expert, a prolific entrepreneur and inventor who holds over 100 patents. Timekeeping might be the unsung hero of human ingenuity. The ...

For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of fundamental theories. But researchers at JILA, led by ...

The world’s network of atomic clocks is already mind-bogglingly accurate. They also underpin a slew of modern necessities, from GPS to internet communication. Atomic clocks work by tuning a laser to ...

Most of the atomic clocks in the world — fewer than 500 in total — are housed at standards institutes and used to keep time for the planet. But the one inside UC Berkeley’s Kolkowitz Lab has a ...

Nearly eight decades after the invention of the atomic clock, scientists in Vienna and Beijing have independently developed the world’s first two operating nuclear clocks, marking a significant ...

Timing is everything in modern warfare, where even a nanosecond’s delay can make the difference between hitting or missing a ...

Pictures of the components used in making an atomic clock. The ion trap (left image) holds the clock in place. The optical/laser apparatus (right images) measures the clock’s frequency. Fukuoka, Japan ...

Vietnamese-born scientist Hoang Thai is leading research at NASA’s Jet Propulsion Laboratory to make ultra-precise atomic clocks small and rugged enough for deep-space missions. The principal ...
