For many centuries, and continuing today, a primary application of accurate clocks is for precise navigation. For example, GPS enables us to determine our distance from the (known) positions of satellites by measuring the time it takes for a pulse of radiation emitted by the satellite to reach us. The more accurately we can measure this time, the more accurate our position is known.
