Concurrently, advances in rubidium atomic frequency standards have pushed the short-term stability to the 10 −14 τ −1/2 regime.

In the Optica Publishing Group journal Optics Letters, Jones and colleagues describe an optical atomic clock that uses a frequency comb to directly excite a two-photon transition in rubidium-87 atoms.

As a world leader in the research, development and manufacture of atomic clocks, Microchip has delivered more than 275,000 rubidium clocks, 120,000 chip-scale atomic clocks (CSACs), 12,500 Cesium ...

While some are enhancements to original atomic-clock architectures based on controlling and counting the atomic-scale energy-level transitions of cesium and rubidium, many are not.

Three high-accuracy space clocks aboard Like its predecessor, GIOVE-B carries two redundant small-size rubidium atomic clocks, each with a stability of 10 nanoseconds per day.

India plans to launch a backup Indian Regional Navigation Satellite System spacecraft in August to replace the ailing IRNSS-1A satellite, which has seen all three of its rubidium atomic clocks fail.

This is a prototype rubidium “atomic clock” developed for Block I Global Positioning System (GPS) satellites about 1974. It dates from the “concept validation phase” of the program, from 1974 through ...
