Experimental Analysis of Frequency Transfer Uncertainty

An experimental analysis of frequency transfer uncertainty is carried out. In situations where at least two transfer techniques are available a first difference statistic is used to determine the type and level of the transfer noise for transfer methods such as common-view GPS, carrier-phase GPS, and two-way time transfer. Frequency transfer uncertainties approaching 1times10-16 at 30 days are possible. A method for estimating the frequency transfer uncertainty in situations where only one transfer technique is available is also examined.
