Object Details maker Tracor, Inc. Tracor Instruments Description Tracor model 304D Rubidium Frequency Standard, Object ID no. 1981.0076.01 This object is a rubidium vapor absorption frequency standard ...

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 ...

Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many orders of magnitude. The clocks, which were put through their paces in ...

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 ...
