The uniformity determination of the machine stroke along the width of the grip by ground method and with the help of the UAV

The possibility of using technical means to assess the implementation of technological operations for land tillage and remote method has been showed. (Purpose of the study) The comparative analysis of ground and remote measurements with the help of UAV in determining the uniformity of the machine's stroke across the working width has been conducted. (Materials and Methods) The toolbox of remote and ground-based measurements has been studied. The results of scientific research has been applied to determine the uniformity of the machine's stroke across the working width, according to the method of GOST 33736-2016. (Results and discussion) The possibility of determining the uniformity of the machine in terms of working width by ground and remote method is analyzed. The coefficient of variation, deviation of the working width from the design width and the standard deviation has been calculated. The coefficient of variation of ground and air measurements has been calculated - 12% and 15% respectively, air measurements are more reliable. It has been determined that aerial measurements will eliminate subjective evaluation when performing technological operations. (Conclusions) The algorithm for determining the uniformity of machine movement by remote method, taking into account the parameters of ground measurements has been developed.
