Rubidium is an alkali metal in group IA of the periodic table with atomic number 37, an atomic weight of 85.47, and a density of 1.53 Mg/m 3. Its melting point is 38.9 C, and it boils at 688 C. The ...

The first nine satellites launched between 2013 and 2023 as a part of NavIC carry imported Rubidium clocks ... in the International Atomic Time (TAI) standard, which a number of synced atomic ...

[Art] certainly lives up to his username. His Rubidium-standard atomic real-time clock is surely an example of hardware art. The substrate is a collection of point-to-point soldered perfboard modules.

[W3AXL] picked up a rubidium reference oscillator on eBay at ... where he actually converts the GPS-discipline oscillator to use the new atomic clock. We’ve seen this done before, of course.
