“…However, this method does not permit consideration of flicker noise frequency modulation, since the quantity becomes infinite. Nevertheless, E [ € ; ] can be expressed as a function of The main noise is frequency flicker noise for sampling durations from 1 month t o 18 months [ 9 ] . In the following we consider the case of the prediction of the scale frequency for simulated calibrations arising from two independent standards, as shown in 1.…”

“…The time scales maintained by independent national laboratories, AT(i), and the individual clocks comprising their clock ensembles, are employed by the BIH to establish a mean International Atomic Time scale [5], TAI, from which a version stepped in units of exactly one second, UTC(BIH), is derived. Each national laboratory then maintains, in addition to its own AT(i), a UTC(i) which may be steered in terms of both time and frequency so as to approximate UTC(B1H).…”

The method of generating the NRC atomic time scales UTC(NRC) and AT(NRC) is outlined, and estimates of their uniformity are derived from intercomparisons of the NRC primary standard, Cs III, and the group of atomic clocks maintained at NRC. Comparisons between UTC(NRC) and other national scales through reception of television and Loran C signals are outlined, and it is shown that conflicting results arise from these two methods. In addition, the uniformity of UTC(NRC) deduced from these comparisons appears to be significantly worse than that determined from internal clock comparisons. Variation in signal propagation delay for both TV and Loran C transmissions is proposed as a possible explanation both for the disagreement between TV and Loran C time scale comparisons and for the apparent degradation in the uniformity of UTC(NRC).
