This is the case whether we are describing a wristwatch with a quartz crystal oscillator or an atomic clock whose oscillator is made up of atoms undergoing quantum energy transitions. A crystal ...

They are so precise that a clock like the Deep Space Atomic Clock is estimated to take 10 million years to lose 1 second of accuracy. Rugged enough to survive space travel while also stable enough ...

On the Deep Space Atomic Clock, this correction is calculated and applied to the quartz oscillator every few seconds. But that's not all that makes the Deep Space Atomic Clock special.

DSAC technology uses the property of mercury ions’ hyperfine transition frequency at 40.50 GHz to steer the frequency output of a quartz oscillator to a near-constant value. The clock confines the ...

How a Toaster-Sized Atomic Clock Could Pave the Way for Deep Space Exploration NASA’s Deep Space Atomic Clock is now orbiting Earth for a year-long test run Jason Daley - Correspondent June 26, 2019 ...

Although a MEMS-based oscillator appears to be straightforward, the development work required to achieve performance comparable to quartz crystal oscillators has been significant. Quartz crystal ...

Optica – Tight real-time synchronization of a microwave clock to an optical clock across a turbulent air path For greater phase coherence at Fourier frequencies beyond the effective synchronization ...

The new Ruby Quartz COM2 Series Surface Mount Clock Oscillators are being quoted at a two to three week basis for sample requests with pricing for production quantities currently $1.00 ea. in lots ...
