Abstract
The invention pertains to transmission to a remote station, by means of transmission channels (generally radio transmission channels), of seismic data acquired by a data collection equipment comprising a plurality of acquisition units, each being suited to acquire, to store and preferably to compress the data to be transmitted. The invention comprises ordered storage, in a high-capacity memory (flash type memory for example) of each acquisition unit (Ai), of data obtained during successive emission-reception cycles (acquired and possibly preprocessed seismic data) so as to form a stream of stored data to be transmitted, and progressive transfer of the stored data stream from each acquisition unit to the remote station by means of the transmission channel, by reading each storage memory, with a time lag in relation to the time of their storage depending on the transmission rate of each transmission channel and on the transmission mode selected with preferably, if sending of the data of a cycle is delayed, sending of at least partial data, compressed or not, for quality control purposes. The data transmitted are reconstituted at the remote station. The method can be used for large-sc…
