A method is provided for the transfer to a central recording device of data corresponding to signals received by a set of seismic sensors which have been sampled, digitized and stored by a plurality of data acquisition apparatus and a device for implementing same, said process including the storage of data in static memories disposed in each of said apparatus, at the end of each recording session moving to the vicinity of each of them a mass memory associated with the device for transferring the collected data into this mass store over a high flow rate connection (cable, wide band short wave link, modulated light beams etc.) and the direct transfer of the data from the mass store to the recording device, a relatively narrow band radio link providing the direct transfer of recording or test data between the apparatus and the central recording system.
A method for transferring to a central control and recording assembly data corresponding to signals received by a set of seismic sensors spaced apart along a seismic profile to be prospected that is remote from said central control and recording assembly, in response to vibrations transmitted and reflected back by discontinuities in the subsoil, during successive transmission-reception cycles, these signals being collected by a plurality of acquisition apparatus adapted for sampling, digitizing and storing the signals received, said method including the steps of:
