Automatic guidance system FARMSTAR-F3

high-precisioncurvilinear

Overview
Agricultural autosteering system for tractors, designed for farms and operators managing passes, implements and fleets. Stated pass-to-pass accuracy of ±2.5 cm. Integrates navigation, real-time monitoring and slope compensation, and supports ISOBUS implement management and Hi-FMS for sharing guidance lines across tractors.

Problems addressed

• Overlaps and missed areas between passes.
• Routes that must adapt to curves, boundaries and headlands.
• Slow operations (e.g. transplanting) that need dedicated guidance.
• Need to share guidance lines and work data across multiple tractors.

Key features

• Stated pass-to-pass accuracy: ±2.5 cm.
• General operating speed range: 0.1–30 km/h (stated as a general range; check GNSS configuration and correction availability for specific operations).
• Support for AB, A+ and curved guidance lines, plus dedicated routes for transplanting and harrowing.
• ISOBUS compatibility with prescription maps and TC-GEO / TC-SC functions for compatible implements.
• Hi-RTP PPP positioning (subject to checks on local coverage and L-band option).
• Real-time monitoring and slope compensation.
• Hi-FMS for centralising farm data and sharing guidance lines across tractors.
• No angle sensor required to provide guidance (tractor compatibility must still be checked).

Advantages

• More consistent field coverage — reduces overlaps and missed areas.
• Guidance at low speeds — operation from 0.1 km/h supports slow tasks such as transplanting.
• Routes suited to the terrain — curved lines, boundary management and slope compensation for varying field geometries.
• Compatible implement management — prescription maps and ISOBUS functions (TC-GEO, TC-SC) for compatible implements.
• Data continuity across tractors — Hi-FMS shares guidance lines and retains operation history.

How it works

• Check machines and implements — verify tractor and implement compatibility for the planned operation.
• Check positioning and corrections — define GNSS configuration and confirm correction availability; for Hi-RTP check local coverage and the L-band option.
• Choose the guidance line — select AB, A+, curved lines or dedicated routes according to field geometry and operation.
• Manage work and data — use real-time monitoring, ISOBUS functions for compatible implements and Hi-FMS to share lines and retain operation history.

Applications

• Straight-line operations — AB and A+ lines for parallel passes and regular spacing.
• Guided transplanting — dedicated lines and low-speed support.
• Guided harrowing — dedicated routes for harrowing paths.
• Irregular fields — curved lines, boundaries, headlands and slope compensation for varying terrain.
• Prescription-based application — prescription maps and ISOBUS functions for compatible implements.
• Fleet management — Hi-FMS centralises farm data and shares guidance lines across tractors.

FAQ (selected)

• What performance is stated for FARMSTAR-F3? Stated specifications: ±2.5 cm pass-to-pass accuracy and a general operating speed range of 0.1–30 km/h. The speed range is general; check GNSS configuration and correction availability for specific operations.
• Is an angle sensor required? No. The system provides guidance without an angle sensor, though tractor compatibility still needs checking.
• Can I use it with any implement? Implement compatibility must be checked. The system supports control of compatible ISOBUS implements, with prescription maps and TC-GEO and TC-SC functions.
• Which guidance lines can I choose? AB, A+ and curved lines are available, plus dedicated lines for transplanting and harrowing. Functions for boundaries, headlands and slope compensation are provided.
• What should I check before using Hi-RTP PPP? Check local Hi-RTP service coverage and the L-band option, plus GNSS configuration and correction availability.
• How are lines shared across multiple tractors? Hi-FMS enables lines to be shared across tractors and centralises farm data, retaining operation history.
