Contemporary automatic guidance research and development has largely utilized highly accurate but expensive real-time kinematic GPS systems for position determination. In this paper, an approach for guiding a vehicle using a lower-cost Differential Global Positioning System (DGPS) receiver is highlighted. The system was successfully implemented on a high-clearance field sprayer at speeds up to 6.7 m/s (15 mph), and was found to have good convergence and tracking ability.
