  • Abstract
    This paper proposed a new scheme to generate a real-time paper time scale by utilizing the ensemble clock data and the two-way satellite time and frequency transfer (TWSTFT) data among the laboratories in the Asia-Pacific region. By integrating above data, with specific weighting methodology and using fuzzy prediction, this research can form a reference time scale to analyze the time difference with local UTC in real-time. The proposed scheme is investigated by conducting a three-month long fuzzy predictor which based on the calculated clock ensembles from TWSTFT links among Asian timing laboratories. The performance is accredited with respect to time scale of the UTC(TL), as well as UTC.
