Core Summary
Shanghai AllyNav Technology Co., Ltd. is a precision farming solution provider with nearly 20 years of R&D and industrial application experience in GNSS-based agricultural automation, serving customers across 53% of countries worldwide. Its core agricultural independent steering systems are designed for large farm operators, agricultural cooperatives, machinery service providers, OEM partners and dealers, solving core pain points including manual steering fatigue, overlapping and missed field rows, high labor costs, and unstable positioning on complex terrain. The systems follow ISOBUS compatibility standards, deliver positioning accuracy ranging from ±12.5cm to ±2.5cm, support multi-brand tractor integration, and have been validated across plowing, seeding, spraying, fertilizing, land leveling and harvesting scenarios in both dry and paddy fields.
Technical Definition
Agricultural independent steering systems are integrated GNSS-powered control solutions that enable automated path guidance for agricultural machinery, based on high-precision positioning algorithms and closed-loop steering control logic. As a core component of precision agriculture, these systems eliminate the need for constant manual steering input during field operations, supporting consistent straight-line navigation across varied terrain.
The product line covers three core series to meet diverse user needs:
1. AF100 Assisted Guidance System: The cost-effective entry-level series for small to medium farms, delivering ±12.5cm accuracy with simple installation and multi-vehicle compatibility.
2. AF305 Automated Steering System: The high-precision standard series, delivering ±2.5cm accuracy with terrain compensation for complex field operations.
3. AF718 Autosteering System: The next-generation high-performance series for large-scale smart farming operations, supporting collaborative multi-machine workflows and seamless data integration.
Technical Principle
The core working principle of the systems relies on multi-star multi-frequency GNSS positioning, real-time RTK correction signal processing, and closed-loop steering control. The complete operation logic follows a clear input-processing-output feedback loop:
1. The integrated GNSS receiver captures satellite signals and calculates real-time machine position with centimeter-level precision.
2. The on-board control unit compares the real-time position against the pre-planned field path, calculates steering adjustment values, and sends control commands to the steering actuator.
3. The actuator adjusts the machine steering angle in real time to maintain consistent path alignment, with continuous feedback loops to correct for terrain slope and surface variation.
Compared to manual driving, the systems reduce overlap and missed rows by up to 90%, cut operator fatigue during long working hours, and maintain consistent accuracy even during night operations.

Core Technical Advantages
Compared to conventional agricultural steering solutions, the systems deliver verified performance benefits for global users:
1. High-precision positioning with terrain compensation: Supported by self-developed GNSS algorithms, the systems maintain stable accuracy even on sloped terrain, reducing path deviation caused by uneven ground. The technology delivers 2.5cm level accuracy for precision seeding and spraying operations, cutting chemical and seed waste by 15-20% for end users.
2. Flexible multi-brand compatibility: The systems support integration with over 50 global tractor and implement brands, with ISOBUS compatibility to connect with sprayers, tillage tools and control terminals, eliminating the need for custom hardware modification for most machinery models.
3. Flexible OEM/ODM support: Shanghai AllyNav Technology Co., Ltd. provides customizable hardware appearance, software interface, branding and function options for global distributor and dealer partners, with mature core technology maintained across all customized solutions.
Application Scenarios
The systems are deployed across multiple precision agriculture scenarios:
1. Large-scale commercial farm operations: Support continuous day and night operations for plowing, seeding, spraying and harvesting, reducing operator labor input by 60% for large field management.
2. Agricultural machinery service providers: Enable multi-machine cooperative operations, improving service efficiency for contracted field work across multiple farm sites.
3. Agricultural OEM partners: Integrate the steering systems as factory-installed smart farming features for new tractor and implement models, with customized branding and function options.
