Atomic clocks for ensemble time scales

NIST intends to construct two ensemble time scales to serve as resilient sources of time/frequency signals and as “backup” implementations of UTC(NIST), NIST’s realization of Coordinated Universal Time. An ensemble time scale consists of several independent atomic clocks, whose outputs are intercompared and usefully averaged together in a way that reduces bias, noise, and dependency on any one clock.
