A seismic acquisition system divides a survey terrain into a number of cells (14) each containing a cell access node (16) and a number of geophone units (10). The geophone units (10) transmit data in digital form to the respective cell access node (16) by wireless telemetry, and the cell access nodes (16) forward the data to a central control (12) by broadband channels.
L'invention concerne un système d'acquisition sismique divisant un terrain d'étude en un certain nombre de cellules (14), chacune contenant un noeud (16) d'accès à la cellule et un certain nombre d'unités géophones (10). Les unités géophones (10) transmettent des données sous forme numérique aux noeuds (16) d'accès aux cellules respectifs par télémétrie sans fil, et les noeuds (16) d'accès aux cellules transmettent les données à une commande centrale (12) par des canaux à large bande.
