Frequency metrology

Frequency metrology is the science of measuring and defining precise frequencies, which relate to the cycles of electromagnetic waves like microwaves or light. It involves developing highly stable and accurate references, such as atomic clocks, to ensure consistency in measurements. These measurements are essential for technologies like GPS, telecommunications, and scientific experiments, where exact timing and frequency standards are critical. Essentially, frequency metrology establishes the “yardstick” for time and frequency, enabling synchronized and reliable electronic systems across various industries and research fields.
