Hardware Delay Measurements and Sensitivities in Carrier Phase Time Transfer

Edward Powers, Paul Wheeler, David Judge, Demetrios Matsakis

Abstract:	Precise time and frequency transfer experiments using GPS carrier phase with time stability less than one hundred picoseconds are now being reported. Strong daily variations in some of the data reported indicate temperature sensitivity in the measurement hardware. The environmental dependence of the instrumental delays of a commonly used carrier phase GPS receiver, its antenna, and several types of antenna cable are reported in this paper.
