FARMSTAR-F3 Auto-Steering System

The FARMSTAR F3 Auto-Steering System is a high-precision GNSS-guided agricultural steering solution that delivers ±2.5 cm pass-to-pass accuracy, automated U-turns, multi-line guidance, slope compensation, and full ISOBUS compatibility. With fast setup, cloud-based farm management, and support for speeds from 0.1 to 30 km/h, it boosts farm efficiency, reduces input waste, and maximizes yield performance across all field operations.

Description

The FARMSTAR F3 Auto-Steering System is a next-generation precision agriculture control platform designed to transform field operations through highly accurate GNSS steering, intuitive software, and intelligent automation. Engineered with over two decades of GNSS expertise, the F3 provides farmers with reliable ±2.5 cm pass-to-pass accuracy—allowing perfect row alignment, optimized crop spacing, reduced overlaps, and improved resource efficiency.

Built as a powerful all-in-one solution, the F3 integrates navigation, a precision computing board, and radio communication into a compact unit that installs easily on any tractor, sprayer, or agricultural implement. Its advanced algorithms support smooth steering at speeds between 0.1–30 km/h, all without needing a front angle sensor. The result is simple setup, accurate guidance, and seamless operation across a wide range of field conditions.

The system features intelligent functions such as automatic U-turn, skip-row turning, slope compensation, multi-line guidance, and fast line nudging, enabling operators to maintain continuous productivity while eliminating manual steering errors. Whether plowing, planting, spraying, or ridge forming, the F3 improves field uniformity and reduces fatigue during long shifts.

With ISOBUS compatibility, the FARMSTAR F3 connects effortlessly to modern agricultural implements, allowing real-time implement control and optimized machine performance. Its cloud-based HiFarm platform enhances field and fleet management by enabling remote data sharing, workline synchronization, boundary handling, and simplified planning between multiple tractors or operators.

Farmers can choose between a 10.1-inch portable touchscreen or a larger 12-inch display for enhanced visibility during complex field operations. Both displays are bright, durable, and engineered for sunlight readability, ensuring excellent visibility in all working environments.

Designed for reliability, the FARMSTAR F3 features IP67-rated durability, industrial-grade components, and a GNSS receiver that supports all major satellite constellations including GPS, GLONASS, Galileo, BDS, QZSS, SBAS, and L-Band correction signals such as Hi-RTP PPP.

From navigation to integrated farm management, the FARMSTAR F3 provides a future-ready auto-steering solution that supports higher yields, lower costs, and smarter farming operations.
