Marine refraction seismic survey system

摘要

The present invention relates to a marine refraction seismic wave survey system, performing a control command of a sound source and a data recording device when a marine refraction seismic wave survey is performed by including a blasting time synchronization system, which comprises: a GPS receiver; a micro controller receiving a pulse per second (PPS) signal from the GPS receiver in accordance with start signal input by a user and independently transferring the PPS signal as a command signal per every predetermined time interval; and a key signal interval controller setting the time interval.
