time and frequency metrology

Time and frequency metrology is the science of measuring time intervals and frequencies accurately. It ensures that clocks and timing devices around the world are synchronized and precise, which is crucial for various technologies like GPS, telecommunications, and scientific research. This field involves using highly precise instruments, such as atomic clocks, which measure oscillations of atoms to define the second. By maintaining consistent and accurate time standards, time and frequency metrology helps facilitate global communication, navigation, and the operation of countless systems in our daily lives.
