Abstract The realization methods of time transfer link calibration have been elaborated, and with the calibration case implemented by National Institute of Metrology (NIM), the uncertainty has been evaluated as about 2 ns, and the efficiency of the methods has been illustrated and verified. Study on the calibration for time transfer links at NIM has been summarized and the future work and prospective are proposed.
