Modern navigation system DGPS as a function of saving in agriculture

Abstract

This research was based on the exploitational analysis of the navigational devices by a family farm from eastern part of Croatia - location Bilje. The research developed into the assessment of the total overlapping surface which ocurred during with and without navigation. The difference between estimated surfaces of overlaps formulates total reduction of the surface of an overlap. Calculations confirm that this farm managed to decrease the surface of the overlaps from 364 ha to much smaller number of 152 ha just by usingnavigation, which totals to a difference of 211,74 ha (58,24 %). The farm was able to process an area of 5 364,06 ha in all operations, where 364,06 ha was lost on overlapping without the use of navigation. Larger manufacturers have better possibility and the need to install new technologies to a greater extent, where savings are in much bigger numbers. In order to make proper use of a navigational system, it is necessary to invest additional resources so that the system can be equipped with an automatic section control. The automatic section control demands additional investments in devices that control the work of the section.
