A method of controlling seismic data acquisition may include sending a first message to place a plurality of energy sources into an operating mode; sending a second message to place at least one of plurality of energy sources into a non-operating mode; and sending a third message from at least one energy source to a controller.

Method of seismic source independent operation

A method of controlling seismic data acquisition includes 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; and delaying sending a start signal to one or more seismic sources, the delay being with reference to a GPS timing signal from a second GPS device.
