Abstract GPS clock is used for synchronizing microtremor data acquisition system to reach good consistency among the devices used in microtremor exploration. Detailed technical scheme and test result is given. It is shown that the accuracy of clock synchronization is better than 0.1 ms,suitable for array microtremor observation.
Key words ：
