Abstract: A network distributed seismic data acquisition system comprises seismic receivers, connected to remote data acquisition modules, receiver lines, base line modules base lines, a central recording system and a seismic source event generation unit. A Global positioning system antenna is positioned at many or all seismic receiver take-out points. Each antenna is supported by minimal antenna signal processing circuitry for transmitting antenna reception to a base GPS receiver having full GPS signal processing capability for determining the distinctive global position of each antenna.
