Abstract
Described are methods of and systems for seismic exploration wherein a master station and a plurality of slave stations are utilized in conjunction with remotely located seismic sources. The system includes apparatus at the master station for generating a start signal and transmitting that signal over single frequency radio link to each of the slave stations. Upon receipt of the start signal at the slave stations the seismic sources are energized in a preprogrammed mode. The field time-break and signature of the seismic energy is acquired and transmitted via the same radio link to the master station. The time-break of one of the sources is transmitted in real time and thereafter each slave station is polled or interrogated by the master station to transmit via the same radio link the time-break and amplitude data representative of the signature of each of the sources before the generation of the next start signal.
