Precision agriculture is no longer reserved for large-scale farms - more and more farmers are realizing that automatic steering and GPS-based systems offer real advantages in daily operations.
However, many are still unsure how these systems work and whether they are worth the investment. This overview helps you understand the essentials.
If you prefer practical examples, you can also watch it in this video.
What is GPS in agriculture?
GPS is satellite-based positioning that shows exactly where the machine is moving in the field. It helps with repeating rows and following working paths.
Its basic accuracy is about 15-30 cm, which is sufficient in many cases but not always enough for precision tasks.
What is a guidance system?
A guidance system is based on GPS data and provides visual assistance to the operator. The display shows how far the machine deviates from the ideal path.
It does not steer the machine but helps avoid overlaps and gaps, saving time and input materials.
What is automatic steering?
With automatic steering, the operator no longer controls the tractor - the system does. The machine follows the predefined path automatically, with centimeter-level accuracy.
This reduces operator fatigue and ensures more consistent work.
Example: Gemini automatic steering
What is RTK and why is it important?
RTK is a correction system that improves GPS accuracy to 2-3 cm.
It allows the machine to follow the exact same path even days or weeks later.
It is especially important for seeding, inter-row cultivation, and precision spraying.
How do these systems work together?
GPS provides the base positioning. The guidance system shows the ideal path. Automatic steering follows it, while RTK fine-tunes the accuracy.
Together, they ensure precise operation with minimal overlap and error.
Why is it worth using?
- Lower fuel consumption
- More precise application (fertilizer, spraying)
- Less overlap and fewer missed areas
- Reduced operator fatigue
- Higher efficiency
Even in medium-sized farms, the investment can pay off quickly.
Summary
GPS, guidance systems, automatic steering, and RTK together form a solution that significantly increases efficiency and reduces costs.
