| Abstract: | This paper comes up with an improved solution of the synchronous acquisition systems.GPS timing set up starting acquisition time in advance and generate trigger signals when the devices with GPS timing detect that time comes,then it can be used to synchronize distributed data acquisition devices.Theoretical analysis and simulation results show that this method can reach microsecond level of time synchronization. |

| Keywords: | FPGA GPS timing synchronization control FPGA microsecond level of time synchronization |
