The main concept of precision agriculture is optimization, which means the precise use of resources, be it fertilizers, pesticides or irrigation water, which has positive effects on the environment. As a result, product quality is improved, and energy consumption decreases significantly. More and more, agricultural technology companies include GPS satellite navigation systems in their product catalogue. From the simplest, with the manual direction to the best, with automated section and assisted steering. So GPS systems are being searched by Romanian farmers. Satellite guidance systems can be mounted on any farm equipment on the holding, regardless of the brand, provided they have power steering. With regard to the precision of GPS systems, there are several models on the market, from the simplest, with a manual direction, which provides a 30 cm accuracy between two passes to the most advanced, with automatic assisted steering, which has an accuracy of 2 centimeters between passes. Thanks to the technology that has advanced a lot in the past, as an example, the GNSS receiver Topcon AGI-3 can receive signals from all existing satellite constellations, GPS, GLONASS, Galileo, EGNOS, using 72 universal patented by Topcon. Galileo, EGNOS and Copernicus satellite communications offer high positioning precision, with a very important role in many domains. Thus, an addition to this project, automated guidance technologies for agricultural machinery, would be to detect and avoid obstacles that may appear on the ground. Also, animals that have a localization chip can be identified within a 20 meter radius of the machine, with rover software, as well as individuals with a mobile phone, or any device that receives a signal from satellite systems.
