Rubidium standard - Wikipedia

A rubidium standard or rubidium atomic clock is a frequency standard in which a specified hyperfine transition of electrons in rubidium-87 atoms is used to control the output frequency. It is the most inexpensive, compact, and widely produced atomic clock, used to control the frequency of television stations, cell phone base stations, in test equipment, and global navigation satellite systems like GPS. Commercial rubidium clocks are less accurate than caesium atomic clocks, w

Rubidium chemical element Britannica

Rubidium atomic clocks, or frequency standards, have been constructed, but they are not as precise as cesium atomic clocks. However, aside from these applications, rubidium metal has few commercial uses and is of very minor economic significance. High prices and an uncertain and limited supply discourage the development of commercial uses.
