Abstract

See full text

A center-pivot irrigation system having a plurality of towers interconnected by a plurality of spans actuatable about a center pivot, a plurality of solid-state sensors each mounted in fixed alignment with one of the spans or towers, and a control system communicably coupled with the solid-state sensors. The solid-state sensors may send acceleration, angular acceleration, angular rotation, heading, and/or angle measurements to the control system, which may use these measurements to calculate alignment of the spans relative to each other and/or the center pivot and to calculate locations of the spans or towers using a known location of the center pivot. The solid-state sensors may be solid-state gyroscopes, solid-state accelerometers, digital compass, and/or an inertial measurement unit (IMU).
