An automated and integrated positioning control system has been developed to improve the accuracy and repeatability of 4D surveys. The control system replaces the need for operator intervention with automated updates to all active seismic elements—vessel, source, and streamer steering devices. The updates are derived from the real time integration of positioning information from in-sea equipment, environmental information, and the survey plan.
