Abstract
A seismic data recording system includes a central station and a plurality of remote seismic data recording units that are deployed within a desired region relative to the central station. The differential locations of the remote recording units relative to the central station are determined by receiving and recording electromagnetic positioning signals at the central station. A portion of the electromagnetic positioning signals is concurrently received and recorded at the respective remote recording units. The portion of the positioning signals recorded at each remote recording unit is combined with the recorded positioning signals from the central station to determine the required differential locations.
