Abstract

Several Polish scientific and commercial institutions are equipped with caesium frequency standards, which can be used for the establishment of a national atomic time scale. The Polish atomic time scale will be computed from a weighted average of the readings of these clocks. All participating laboratories are equipped with a multi-channel GPS C/A code Time-Transfer unit. The structure of this unit is described in brief: the multi-channel method improves the stabilty of the time transfer compared with the single-channel method. The results of such comparisons are presented
