Abstract:

A new measurement for highprecision time interval is provided to satisfy the present precision requirement of the time synchronization. Utilizing the own periodicity of 1pps signals, the multi-level time interval measurement and correction is put forward to keep time synchronization, in which the measured time interval is high-precisely measured and corrected under different time interval conditions. Experiment shows a ±24ps resolution and accuracy is reached. 
