Sveaverken F200 Auto Steer System

The Sveaverken F200 is a hardware-retrofitted, automated steering system engineered for agricultural tractors and machinery. The system utilizes real-time kinematic (RTK) differential positioning alongside an automated mechanical steering drive to achieve automated path tracking across field operations. Guidance, Satellite, and Telemetry Systems Spatial Precision Margin: The system achieves a pass-to-pass accuracy threshold of $\pm$2.5 cm when connected to an active RTK correction network. Constellation Compatibility: The onboard GNSS receiver tracks multi-frequency signals across major satellite networks, including GPS, GLONASS, BeiDou, and Galileo, maintaining signal locks during partial horizon obstructions. Correction Input Methods: Supports differential corrections via internal UHF Radio (410–470 MHz) for base-station configurations and NTRIP (cellular network) protocols. Attitude Compensation: An internal Inertial Measurement Unit (IMU) calculates real-time pitch, roll, and yaw variations at high frequencies, dynamically adjusting steering vectors to compensate for sloped terrain and uneven soil conditions. Control Terminal and Mechanical Assembly Display Interface: Operations are managed via a 10.1-inch capacitive touchscreen terminal running an Android-based operating system. The interface displays real-time path deviation data, speed tracking, and field mapping boundaries. Actuator Drive: The factory steering wheel is replaced by a high-torque, brushless electric steering motor wheel. The direct-drive configuration interfaces with the vehicle's steering column via standardized spline adapters, eliminating mechanical backlash. Operational Patterns: Built-in calculation modules support multiple guidance patterns, including Straight Line (A-B Line), Adaptive Curve, and Pivot path generation. Physical and Electrical Integrity Voltage Range: Compatible with standard heavy machinery electrical architectures, operating within a 12V to 24V DC input window. Environmental Protection: External components (GNSS antenna, steering actuator) carry an IP67 ingress rating, ensuring complete sealing against dust and high-pressure water exposure. Internal cab hardware carries an IP65 rating.
