1. A method for synchronization of systems for seismic surveys and of subsystems of said systems, said systems being selected from the group consisting of land-based systems, marine-based systems, and a combination thereof, and said subsystems being selected from the group consisting of at least one navigation system, at least one seismic signal generating system and at least one recording system comprising:

  • supplying a survey system with an absolute time standard;

    generating via a time code generator in said survey system a time code based on said absolute time standard;

    providing at least one programmable event generator in said survey system;

    connecting said event generator with said time code generator;

    synchronizing said event generator with said absolute time standard;

    predetermining the time for a defined event on the basis of given parameters;

    providing the time for a defined event with said time code corresponding to a point in time;

    supplying the time for said defined event to the respective subsystems;

    continuously supplying said subsystems with said absolute time standard; and

    executing said defined event in at least one respective subsystem on the basis of said continuously supplied absolute time standard.
