Differential correction systems in autopilot RTK differential and geostationary and quality of the sowing pneumatic and mechanical

Abstract

Such as differential correction systems, which are essential for the accuracy of the parallelism of vehicle guidance systems as for the quality of the seeding operation. Therefore, the objective of this work was to evaluate the accuracy of the autopilot - guided passes under RTK differential and geostationary satellite systems involved in pneumatic and mechanical sowing of corn; as well as to analyze the quality of the sowing operation using the plant stand as indicator. Two treatments were analyzed: autopilot RTK (Real Time Kinematic) and geostationary satellites, used in sowing operations. The evaluations were carried out under field. The use of autopilot with RTK differential correction in corn sowing operations offers greater accuracy between passes than that obtained with satellite correction. As to the quality of the sowing operation, the pneumatics show a better regularity in the distribution of corn seeds.
