When Dusty LeBrun of Sioux Falls, S.D., headed out to plant corn last spring, he had the latest precision ag technology along for the ride. The technology is a unique convergence of two existing technologies-Real Time Kinematic global positioning system and cellular technology.
Farmers have been using GPS guidance systems to precisely plant and spray crops for several years. It is available day and night and reduces overlap, which saves seed and chemical expenses and minimizes operator fatigue. The system works well as long as there is an unobstructed line of sight to the base station or repeater tower and as long as the operator is within about six miles of the base station or repeater tower.
