Abstract：Aiming at the contradictory between measurement range and resolution in the traditional time synchronization technology,a high-resolution time synchronization detection method with wide range is proposed on the basis of time interval measurement.Using the accuracy and stability of electromagnetic wave signal transmission in a specific medium,combining the different frequency phase detection principle without frequency normalization between any signals,and based on the conversion of time and space relations,a time-frequency measurement technique based on length vernier is used in navigation satellite for the synchronization detection of 1pps signal,which improves the resolution of the time difference measurement of 1pps signal.Moreover,the multi-levels measurement method formed by combining the technique and the traditional time interval measurement method with high precision has a wide measurement range in time and frequency measurement field.It was found that the method is reasonable and scientific in our experiment.Experimental results show that the measurement resolution with 50ps can be obtained in this method,and its stability is better than 10ps.The novel method may be ussful for providing the theoretical guidancethe and the key technical support of time synchronization to the chinese high-tech areas,such as aeronautics and astronautics,navigation and positioning,communication,metrologica,radar,astronomy and so on.
