In frequency domain electric exploration,the authors propose the utilization of the GPS OEM so as to improve the accuracy of signal phase estimation. 1 pps can be used as a time reference. The time synchronization of the frequency domain electric transmitter and receiver can thus be realized. This paper describes the framework, characteristics and principles of GPS in time synchronization. The frequency domain electric transmitter and receiver synchronization electrocircuit has been designed. It is concluded that the GPS time synchronization is feasible in this instrument.
