Agricultural Machinery Engineering 101: RTK Guidance — From Satellite Positioning to Autonomous Steering and Variable-Rate Application
RTK-GNSS delivers centimeter-class position, but by itself it steers nothing. This article works through the engineering chain that makes 'RTK guidance' actually reduce labor and sharpen precision in tractors and rice transplanters: AB-line/curve/contour guidance patterns, the control loop that feeds lateral deviation back into steering angle, and the link to yield and application maps.
