How are atomic clocks synchronized
Web24 de mar. de 2024 · This work shows how the best atomic clocks might be synchronized across remote sites on Earth and, as time signals are transferred over longer distances, even between spacecraft. The key to the air link was the use of optical frequency combs, which enable accurate comparisons of widely different frequencies. WebThe GPS receiver's time has to be synchronized with atomic clocks located in GPS satellites. It is kinda chicken or the egg problem. The receiver needs precise time to …
