Automatic wind-drift compensation system for agricultural sprayers

Agricultural spraying of soil nutrients, insecticides and pesticides is common, and typically involves the use of a boom-type sprayer pulled behind a tractor. Recently, various navigation aid systems have been developed with increased accuracy for steering the tractor through the field on a desired path. Examples of such steering systems include the John Deere Parallel Tracking and AutoTrak system, IntigriNautics AutoSteer products, and systems by Trimble, and Beeline. An automatic wind-drift compensation system is provided for an agricultural sprayer. The system includes a control unit adapted to receive input data including wind speed and direction, vehicle speed and direction, and desired spray overlap. The control unit is programmed with a set of instructions for processing the data and generating output data. The output data facilitates steering of the sprayer through the field to achieve the desired spray overlap.
