Abstract

This paper introduces a method and experiment using free-space, pulsed, optical time transfer, through turbid water to synchronize spatially distant chip-scale atomic clocks. This experiment uses one-way time transfer. Clock discrepancy is computed by comparing the measured departure time from Module A to the measured arrival time at the Module B, after accounting for the estimated time of flight. The effect of the turbidity is calculated and compared through clock discrepancy and time transfer stability for an empty tank, still water, turbid water, and fog.
