The system consists of an online NRTK service, vehicle-mounted RTK receivers, inertial attitude sensors, steering controllers and a display terminal. The base station outputs differential data to ensure centimeter-level positioning accuracy. Integrated with navigation algorithms, it automatically controls the steering, speed and driving route of tractors, planters and harvesters. It follows preset farmland paths to complete seeding, fertilizing and harvesting operations, realizing unmanned and high-efficiency farm work.
