Objectives and competences

The students get acquainted with the basics of control system operation, which are important in practice, with the advantages of using such a system in practice, the basics of positioning and determining the location on the ground, using these systems in practice, the precision of the individual system and the scope of the individual system with respect to accuracy and price of the system. Competences: • ability to understand and put these systems • into practice • ability to identify and solve problems in practice

Content (Syllabus outline)

• • basics of control system (tractor steering): control systems available on the market (supported steering system, automatic steering system) • composition and operation of the control system: space, control and user segment, how DGPS works, Slovenian network • benefits of the steering (automatic) system: advantages of the steering system (comfort, economics) and increasing the efficiency of work with greater precision of work, savings in the use of the steering system (example of saving from the practice at the farm in the light of improving efficiency in the transition to a low-carbon circular economy). • GNSS: relevant GNSS installations for use in agriculture, functionality and positioning with GNSS, the influence of various parameters for positioning on the ground • signal correction and field correction principle, satellite-based signal correction (EGNOS and OMNISTAR), signal correction from the ground (mobile and fixed reference station (RTK), virtual VRS reference station for signal correction connected to the telephone network) • limitations in satellite signal correction and loss of correction signal near trees, buildings, static and dynamic accuracy, signal evasion • the navigation system in the car vs. automatic steering system in the tractor (required accuracy, receiver, sensors, steering) • different accuracy of the signal (± 30 cm to ± 2 cm) according to the signal correction and the possibilities and feasibility of using a particular system in practice (depending on the individual work task) • tractor components needed for the use of GPS device, description and presentation of individual components (signal receiver on the roof, wheel angle sensors, hydraulic system, controller of the control device, terminal) • system operation in practice (concepts and settings of individual operations through the terminal, various applications, automatic measuring of surface, ISOBUS connection, etc.), instant documentation and easy data transfer into different programs for further data processing, connection of the corresponding software and computer equipment (data transfer between tractor and PC) • techniques and procedures of measurements of agricultural land (GERKs), measurement from orthophotos, gps measurements, tolerances of measurements and precision of measurement methods • Precise Variable fertilization of agricultural areas and production of digital maps (nitrogen fertilization based on satellite and drone images, stock fertilization of agricultural areas based on soil analysis) in the light of the green transition and the transition to a low-carbon circular economy. Advantages of variable fertilization farmers areas from the point of view of improving efficiency, higher productivity and better economic efficiency.
