Claim 12:
13. A method of seismic data collection, the method comprising:
(a) determining positional setpoint data for a first towed marine seismic component and a second towed marine seismic component;
(b) utilizing a marine vessel to tow a first cable coupled to the first towed marine seismic component and a second cable coupled to the second towed marine seismic component;
(c) receiving a first set of process data representing a calculated actual position of each of the first and second towed marine seismic components;
(d) computing a difference between the positional setpoint data and the received first set of process data;
(e) measuring a disturbance affecting a course of the first and second towed marine seismic components, the measured disturbance represented by disturbance data, wherein the disturbance data is different than the positional setpoint data or the first set of process data, wherein the measured disturbance comprises one or more of a heading of the marine vessel, a speed of the marine vessel, a speed of a current affecting the marine vessel, or a direction of a current affecting the marine vessel, and wherein a percentage or portion of the measured disturbance value is used to immediately effect changes in control signal to the steering actuator to respond to measurable disturbances before effects of the measurable disturbances are recognized in a feedback loop;
(f) generating control commands for steering each of the first and second towed marine seismic components based on the computed difference between the positional setpoint data and the first set of process data;
g) calculating an anticipated impact of the measured disturbance data on a course of the first and second towed marine seismic components as compared to the positional setpoint data, wherein the calculated anticipated impact is a quotient with the measured disturbance data in a numerator and the first set of process data in a denominator;
(h) adjusting the control commands based upon the calculated impact of the measured disturbance data;
(1) implementing the adjusted control commends by individually steering each of the first and second towed marine seismic components based on the adjusted control commands;
(j) once the adjusted control commands have been implemented, compute computing the anticipated results of the adjusted control commands on the steering of the first and second towed marine seismic components in order to generate a second process data set;
(k) modifying the second process data set utilizing the disturbance data (U); and thereafter,
(l) utilizing the modified second process data in step (c) and repeating steps (d)-(l).
