Abstract
The absolute frequency of the lattice clock transition was evaluated with an uncertainty of using a frequency link to the international atomic time (TAI). The frequency uncertainty of a hydrogen maser used as a transfer oscillator was reduced by homogeneously distributed intermittent measurement over a five-day grid of TAI. Three sets of four or five days measurements as well as systematic uncertainty of the clock at have resulted in an absolute frequency of clock transition to be 429 228 004 229 872.85 (47) Hz.
