The principle to modulate the GPS clock signal with high frequency signal was introduced, the method of decrease the error of time measurement and the design of the circuit were proposed. The result indicated that the GPS clock signal may transform into the a- coustic signal by the transducer, also it can convey in the water medium with undistortion. The regular and much stronger signal was received and disposed by the circuit, which meet the demand for detection and using.
