Abstract
The invention comprises several groups of local units (BA) suited for the acquisition, the processing and the transmission of data collected in the field by seismic receivers, each of these groups being controlled by a local station (LS) equipped to fulfill extensive functions including collection of the seismic data of the various units, management of testing and initialization operations on radio channels and on the field equipment such as seismic receivers (R), electronics in each unit RTU, monitoring of the progress of seismic operations, and reporting on results and possible anomalies. The seismic set comprises several groups (GR) of receivers, with associated local units and a local station, which are placed under the control of a central synchronization, monitoring and control station (SCC) where all the seismic data are finally gathered. The system is applicable to large-scale seismic exploration.
