摘要
Seismic surveying apparatus and method for collecting data acquired during a seismic survey comprises a plurality of data sources 205, each associated with a transmitter capable of transmitting data, preferably wirelessly. The data sources 205 are disposed in a plurality of cells 200 and in each cell 200, one of the transmitters serves as a gateway 210 for receiving data transmitted from the other data sources 205 in the cell. Each data source 205 comprises one or more seismic sensors, e.g. geophones (305 fig. 3). Independent pathways for data transmission are provided by transmitting data from one gateway 210 to another to reach a central location, e.g. a recording truck 110 or fixed-base facility. Data may be transmitted synchronously or asynchronously via a path of gateways 210 and transmission along a path may employ one of frequency division or time division multiplexing. The cells may overlap or be interleaved and relays (RP, fig 8a) may be provided in the paths.
