Abstract:
1. A method for controlling seismic data acquisition communication, comprising: synchronizing a sampling rate of at least one node configured to acquire seismic data with a GPS timing signal from a first GPS seismic device, wherein the sampling rate is defined by time boundaries; sending a start signal to one or more seismic decoders, the start signal initiating a synchronized countdown across the one or more seismic decoders having a delay that is with reference to a GPS timing signal from a second GPS device; receiving the start signal at the one more seismic decoders, wherein the one or more seismic decoders initiate the synchronized countdown upon receiving the start signal; and activating at least one seismic energy source disposed on the one or more seismic decoders at the end of the synchronized countdown, wherein the synchronized countdown ends at the occurrence of a time boundary of the sampling rate of the at least one node.
