Synchronization System Design of Ground Electromagnetic Probe Based on FPGA and GPS

Abstract:

This paper presents a synchronization system of ground electromagnetic probe based on FPGA and GPS. In order to realize precise synchronization between transmitter and receiver, the paper uses the GPS module, the application of GPS-synchronized is a relatively good synchronization mode because of its independent of distance and topography. This paper makes the coordinated universal time of GPS and seconds pulse 1pps as the time reference, analyses synchronization principle and characteristics based on FPGA and GPS, designs time synchronization circuit, realizes the output of the synchronous enable signal. Finally it can realize the precise synchronization between a transmitter and several receivers.
