|Abstract:||We proposed a new GPS (Global Positioning System) ensemble receiver model which CGGTTS (Common GNSS Generic Time Transfer Standard)[1-3] outputs are the weighted results of all calibrated receivers in ensemble for time transfer and calibration. Since the outliers and divergent measurements of all receivers in ensemble are filtered out by weighting procedure, the equivalent total delay of ensemble receiver CGGTTS would be more stationary than any physical receiver in ensemble. The common clock difference and double clock difference tests demonstrate the ensemble receiver is more robust and stable than any physical receiver in ensemble. The double clock difference of long term GPS P3 all in view time comparison and TWSTFT (Two-Way Satellite Time and Frequency Transfer) also demonstrates that the GPS time transfer executed by ensemble receiver is much more stable than the physical receivers both in short and long term.|
