A relativistic synchronization-based experiment for improving the accuracy of time scale transmission

We present experimental results concerning time scale transmission to a remote consumer using a relativistic synchronization. The time scale transmission is carried out using a transportable quantum clock on an automobile chassis moving along federal roads for a distance of more than 5000 km. The results are confirmed by an independent method for comparing time scales using signals from global navigation satellite systems. The error of the relativistic synchronization method does not exceed 150 ps, which is significantly better than when other methods are used.
