Attenuating Day-Boundary Discontinuities in GPS Carrier-Phase Time Transfer

Ken Senior, Ed Powers, Demetrios Matsakis

Abstract:	Many IGS analysis centers show I-nanosecond-level discontinuities across processing boundaries in their GPS carrier-phase time-transfer (GPSCPTT) solutions. Though these discontinuities reflect the nature of processing the GPS data, generally in l-day batches, this paper tests the hypothesis that, with slight modifications in the standard filtering process, one might improve the degrees of freedom with respect to phase ambiguity parameters in such a way as to improve the time-transfer solutions and attenuate most of the discontinuities.
