Precision agriculture is transforming modern farming. Farmers today need to produce more food while reducing labor, input costs, and environmental impact. To achieve this, many farms rely on advanced positioning and guidance technologies.

One of the most important technologies behind modern agricultural navigation and auto-steering systems is Real-Time Kinematic (RTK) positioning.

RTK technology provides centimeter-level accuracy for farm machinery, allowing tractors, sprayers, and harvesters to follow precise paths across the field. With this level of positioning accuracy, farmers can reduce overlaps, optimize input usage, and significantly improve field efficiency.

So what exactly is RTK technology, and why is it essential for modern tractor navigation systems?

Modern agriculture is experiencing continuous transformation. Labor shortages, unpredictable weather conditions, and the increasing demand to produce more with fewer resources are pushing farmers to adopt precision technologies. As a result, modernising agricultural machinery has become an important strategy for improving field efficiency and operational accuracy.

Instead of purchasing expensive new equipment, many farmers choose to upgrade their existing tractors by installing advanced control and navigation technologies.

Among these technologies, the auto-steering system has become one of the most important tools in modern precision agriculture. By integrating automated guidance systems into tractors, farmers can significantly improve field consistency and operational efficiency. These systems are widely used for tasks such as row crop management, tillage, spraying, planting, and other operations that require high precision across large farming areas.

In this step-by-step tutorial, you’ll learn:

• How to prepare your setup

• How to enter SLAM-RTK Mode

• How to perform correct initialization (L-shape / Z-shape walking path)

• How to ensure stable SLAM-Fix in tunnels, basements, indoor areas & under eaves

• How to check SLAM-tagged measurement points after surveying

During the stationary step, avoid significant shaking of the RTK device and keep the receiver still for 3-5 seconds; point it towards features such as buildings and other objects with rich characteristics, and avoid pointing it towards moving vehicles, crowds, or open fields.

During the moving step, choose a relatively open and unobstructed scene to ensure reliable GNSS accuracy; it is recommended to walk in an L-shape or Z-shape path, avoiding straight lines; the longer the walking distance, the better the initialization effect.

Laser-based reverse engineering technology allows for measurements even in weak GNSS signal environments; SLAM image measurement technology supports non-contact measurement; it combines SLAM scanning functionality, offering high integration, long battery life, and simple operation (scene adaptive, no control points required, no loop closure needed, consistent indoor and outdoor coordinate system); and supports rapid stockpile volume measurement without the need for post-processing.
