1. A system for synchronizing and collecting seismic data from a plurality of locations in a seismic field in which a seismic signal is transmitted, said system comprising:

  • a plurality of seismic sensor devices configured to collect seismic information based upon the seismic signal transmitted;

    at least one positioning system receiver configured to receive positioning signals and timing information;

    time control logic configured to compute a time based upon the received timing information;

    a seismic data collection device configured to generate a plurality of records of measurement data comprising seismic information and the time of collection of the seismic information, said time determined by the time control logic;

    a post processor configured to receive the records of measurement data and extract records comprising a time of collection within a specified time window of interest.
