AutoTrac – Accuracy of a RTK DGPS based Autonomous Vehicle Guidance System under Field Conditions

Reference measuring system has proofed practicability. Reference system is able to measure inclinations - accuracy can be improved by an extended antenna spacing. AGRO NAV® was in the specified range of ± 100 mm for speeds up to 10 km/h (for 12 km/h in the range of ± 130 mm). Deviations on a sloped field up to 240 mm caused by yawing of the implement. Planning Software was only able to create jobs in 2D (x-y plane) instead of 3D – sloped contours were not considered. The great potential of RTK DGPS based auto guidance technology for agricultural vehicles was clearly demonstrated.     «
