Nowadays, the agriculture technologies using guidance systems during field operations are more and more common all around the world. Machines without satellite navigation in fields have a tendency to pass-to-pass errors, especially unwanted overlaps, resulting in waste of fuel and pesticides, longer working times and also environmental damage. Finally, such errors can be taken as useless additional costs of farming. When utilising satellite guidance for field operations, the pass-to-pass accuracy can be significantly improved and thus it is possible to make the agriculture production more efficient. The purpose of this paper was to evaluate advantages and real possibilities of using advanced machinery guidance systems with regard to energy consumption and efficiency and also more environmental friendly agricultural operations. Real pass-to-pass errors (omissions and overlaps) in a field were measured on different tractor-implement units with and without guidance system utilization. The outcomes from our measurements revealed that there is a statistically significant difference between the total area treated by machinery without any guidance system and machinery using precise guidance systems. It means, better accuracy of machinery passes in fields with guidance systems could help with energy and material savings. Namely the fuel, seeding material or chemicals can be saved up to 6% from a single field operation.
