Abstract
A guidance system for providing a steering control for a swing arm on a center pivot irrigation system is provided through the use of two satellite signal receivers. A first signal receiver is located at the center pivot to provide calculated position information for a comparison with the known position of the center pivot. An error signal is generated and is utilized to adjust position information provided by the second signal receiver to produce an improved position information for the swing arm. Such improved position information is compared to the desired path of travel for the swing arm and a steering signal is generated therefrom, which steering signal controls the steering of the swing arm along its desired path of travel.
