Abstract
A corner unit guidance control system for use with a corner unit that is part of a center pivot irrigation system includes an antenna, a receiver, and a controller. The antenna may be located along a vertical axis through the center of a wheel of the corner unit and may be operable to receive signals from at least one external positional information source. The receiver may be in communication with the antenna and operable to process the signals to produce position data corresponding to a current position of the wheel. The controller may be in communication with the receiver and may be programmed to steer the wheel to a heading corresponding to a difference between the current position of the wheel and a point along the path.
