Transforming Farming: The Role of Precision Agriculture and Satellite Navigation

Precision agriculture represents a groundbreaking approach to farming, utilizing advanced technology to enhance crop yields, minimize waste, and promote sustainable practices. At the heart of this revolution is satellite navigation (satnav), which allows farmers to access precise geographical data and improve their agricultural practices.

Understanding Satellite Navigation

A satellite navigation system is designed to provide autonomous geopositioning through the use of satellites. This technological marvel offers significant advantages in various fields, most notably in agriculture. When we refer to a satellite navigation system with global coverage, we're talking about a Global Navigation Satellite System (GNSS).

As of 2024, four major global systems are operational:

These systems collectively enable highly accurate positioning and timing information essential for modern precision agriculture techniques.
