Abstract: One of the ways of increasing the efficiency and safety of work is the implementation of navigation systems in agricultural practice. Satellite navigation as a means of reducing the unit costs and increasing the safety can have a significant economic impact on a company when properly used. The objective of measurement was to assess the accuracy of a satellite system AutoTrack working with a correction signal SF2. Its provider specifies an accuracy of ± 5 cm for this signal type. The accuracy of machine work was compared for two scenarios, i.e. with and without satellite navigation. Further, the navigation of machines focused predominantly on AgGPS EZ-Guide Plus and AutoTrac Universal. The FMEA method was used to determine the risk of probable failures that can occur on machines while working. This work describes the individual failures that can occur on navigation systems of machines and analyses their impact on operator's safety.
