Automatic guidance systems on tractors get more and more popular because they contribute to increase the efficiency of agricultural operations in several aspects. Aim of the investigation was to develop a sensing method to allow the assessment of automatic steering systems by quantifying cross track errors. A kinematic tachymeter (total station) was used to track a fixed point (prism) on the moving machine and function as a reference system. Tractors were tested in automatic mode on different routes. Cross track errors were calculated for describing the performance accuracy related to an ideal route. Due to its direct meaning the results for front and rear axle centers (interest points) are presented. The results show that for assuming a realistic positional accuracy of the GNSS system of around 2 cm that the errors are at least doubled in terms of lateral variability of driving trajectories. For higher speeds and partly more rough condition the errors are up to 4 fold the GNSS accuracy. The developed and presented measuring system was able to quantify the accuracy of the driving performance of tractors based on automatic steering systems.
