GPS Guidance System for Agricultural Machinery | Precision Steering Component

Product Specifications

Technical details and manufacturing context for GPS Guidance System

Definition

The GPS Guidance System is a component-level product designed for integration into agricultural machinery. It provides automated steering control based on Global Positioning System (GPS) signals, enabling precise field operations such as planting, spraying, and harvesting. The system reduces operator fatigue, minimizes input waste, and increases field efficiency by maintaining accurate pass-to-pass accuracy.

The system comprises electronic components (including a printed circuit board and processors), an antenna housed in plastic or composite material, a display unit with glass and plastic elements, and a wiring harness with copper conductors and insulation. It is intended for use in agricultural vehicles and implements, and its performance is defined by a set of reference parameters that must be verified for the specific model and application.

Key parameters include positioning accuracy of ±2.5 cm with Real-Time Kinematic (RTK) correction (without correction, ±30 cm), pass-to-pass accuracy of ±2.5 cm, operating temperature range of -40 to 85 °C, input voltage of 9–36 V DC (compatible with 12V/24V systems), power consumption of ≤15 W, IP rating of IP65–IP67 per IEC 60529, 32–64 channels supporting GPS L1/L2, GLONASS, Galileo, and BeiDou, update rate of 10–20 Hz, weight of 1.5–3.5 kg (including antenna and display), display size of 8–12 inches (touchscreen, sunlight readable), communication interfaces including CAN, RS232, and USB, and memory of 8–32 GB for field maps and data logging.

These values are directory reference ranges and must be confirmed with the legal manufacturer or supplier for the actual product. The system is not certified or compliant solely by listing these parameters; verification of standards and performance is the responsibility of the buyer. The product is listed in a neutral directory and is not manufactured or sold by the directory operator.

Working Principle

The system receives signals from GPS satellites to determine the machinery's exact position. This positional data is processed by an onboard computer, which compares it to predefined field maps or guidance lines. The system then sends steering corrections to hydraulic or electric actuators to maintain the desired path, often with centimeter-level accuracy when using RTK corrections. The working principle relies on real-time data processing and actuator control, with an update rate of 10–20 Hz to ensure responsive steering. The system's accuracy is influenced by satellite availability, atmospheric conditions, and the use of correction signals. For optimal performance, the antenna must have a clear view of the sky, and the system must be properly calibrated to the vehicle's dimensions and implement offsets.
