Discover how GPS based steering on tractors, possible by GOcontroll technology, enables creative smart farming solutions like maize mazes in the Dutch countryside.

GPS based steering is redefining agricultural innovation. At Landswinkel Smits in De Heurne (Achterhoek), a maize maze isn’t just a seasonal attraction—it’s proof of what’s possible when tractors are equipped with precision satellite navigation. Let’s explore how this smart farming example puts GPS technology in the spotlight.

GPS based steering refers to using satellite positioning systems to automate and guide agricultural vehicles. When applied to tractors, it brings several advantages:

• Extremely accurate navigation, often to within 2 cm
• Efficient, automated field operations, no overlaps or gaps
• Reduced input costs by minimizing fuel and fertilizer waste
• Improved operator comfort and safety
• Consistent performance, day or night, in any weather

The GOcontroll’s free programmable modular controllers, like the Moduline IV and Moduline Mini I are enabling technologies. These devices allow for real-time GPS data integration and control logic execution using CAN bus interfaces, GNSS modules, and robust output control. Combined with powerful software like MATLAB Simulink and Node-RED, users get full control without needing to write complex code.

At Landswinkel Smits, a yearly maize maze becomes the perfect case study for GPS based steering in action. Instead of manually designing and laying out the paths, the entire process is digitized and automated:

1. Maze Planning: A CAD or map design of the maze is created.
2. Maze layout is programmed into a controller.
3. GNSS Integration: The controller receives live location data and steers the tractor accordingly.
4. Path Execution: With sub-inch precision, the tractor mows or plants according to the maze layout, with minimal human input.

What once took hours of manual labor with flags and tape now takes minutes with GPS guidance and automation. It’s precise, repeatable, and impressively creative.

GOcontroll’s hardware could be used for such projects. The hardware is built for rough field environments and scalable performance:

• Moduline IV: Suitable for complex systems with up to 8 I/O modules, 4 CAN ports, and optional GNSS antenna connectivity.
• Moduline Mini I: Compact yet powerful, perfect for smaller tractors or single-purpose builds.
• GNSS Ready: Compatible with GPS modules and antennas for accurate global positioning.
• Cloud Connectivity: Optional cellular modules allow remote monitoring, updates, and diagnostics.

Software support includes:

• Node-RED: Visual, browser-based programming with GOcontroll-specific GPS and control nodes.
• MATLAB Simulink: Model-based design for building custom algorithms without writing code.
• FOTA (Firmware Over-the-Air): Update multiple systems simultaneously from a central location.

These tools make it easy for system integrators and agricultural engineers to build smart steering solutions.

While maize mazes are a fun use case, the potential of GPS based steering spans across agriculture:

• Precision planting: Optimizing seed placement based on GPS zones.
• Variable-rate spraying: Automatically adjusting chemical delivery per location.
• Contour farming: Mapping terrain and adjusting tractor paths accordingly.
• Autonomous logistics: Coordinating E-axle trailers or autonomous carts.
• Fleet tracking and diagnostics: Monitoring tractors in real-time across the farm.

GOcontroll enables these applications with durable hardware, flexible module options, and software that integrates into any modern agricultural system. The result? Smarter, leaner, and more sustainable farming practices.
