Using satellite navigation for seeding of wide-row and narrow-row crops

Abstract

The present paper is aimed at the use of satellite navigation of field machinery during seeding, this operation belonging to the most important field practises. Our attention was focused on the determination of the accuracy of the satellite navigation system based on using the correction signal real-time kinematic and its correct application for planting a wide-row crop (sunflower) and seeding a narrow-row crop (spring barley). The aim of the field experiment was also to specify the level of the necessary accuracy of satellite navigation systems during planting and seeding. The length of seeding/planting equipment was confronted with the accuracy of navigation of individual passes, especially when turning on the headlands. In the conclusion, the importance is highlighted of the automated tractor headland control during satellite navigation of combined field machines in the crop production.
