rubidium clock

A rubidium clock is a highly precise timekeeping device that uses the natural vibrations of rubidium atoms to measure time. Inside the clock, rubidium atoms are energized using microwaves, causing them to oscillate at a specific frequency. This oscillation frequency is extremely stable and serves as a reliable reference for keeping time. Rubidium clocks are used in various applications, including GPS satellites and telecommunications, because they offer accuracy better than traditional quartz clocks, ensuring synchronized timekeeping essential for modern technologies. Their precision makes them vital for scientific research and global positioning systems.
