Is GPS time synchronization and WWVB Atomic time the same?
No. There are several differences between the two. Primarily the frequency and duration of the transmitted signal, and its reliability. Atomic clocks utilize a 60 kHz AM signal, which is more susceptible to various sources of interference such as weather, electrical noise and building materials, along with the actual physical location of the clock. As a result, the synchronization can be limited, inconsistent and therefore not recommended for commercial facility applications. GPS time is not sensitive to weather or other adverse conditions. The receiver just needs to be located within a clear view of the sky. The KRONOsync™ system signal is rebroadcast in UHF FM 467MHz, making it less prone to interference and much more reliable for building penetration, resulting in accurate, reliable synchronized time.
