A New Technique for Estimating Frequency from GPS Carrier-Phase Time Transfer Data

August 28, 2004

Author(s)

C Hackman, Judah Levine, Tom Parker, Dirk Piester, Juergen Becker

GPS carrier-phase time transfer (GPSCP1T) offers high frequency stability at short averaging times, approaching a fractional frequency stability of 10-15 at averaging times of one day. However, a discontinuity occurs in the time transfer estimates between
