Precision timing application of GPS in wide area power-anglemeasurement system in power system;

Method and Realization of Heading & Attitude Measurement and Positioning & Timing for Target Ship;

Study on the Additional Spread Spectrum Modulation Technique in Low-frequency Time-code Timing Service System;

Research on high precision common-view time service of double-star system;

Research and Realization of Beidou Common-view Time Service Method;

Around the task of developing a time service signal unit for Shanghai Seacoast Broadcasting Station,the new international time signal format is introduced briefly,and a scheme for time transfer based on remote dial communication is presented.

The technique for improving the “Beidou” positioning ability is presented through constituting the terrestrial improvement system, and the beacon synchronization of the improvement system with the “Beidou” one-way time transfer model is realized.

CompassⅠis a new Global Navigation Satellite System developed by china;it has communication and time transfer capability.

The time transfer principle and character of compass I is introduced in this paper,the experimental results is analyzed to assess the time transfer capability of compass I.
