Learning outcomes of the course unit: |
The course provides an introduction to Global Navigation Satellite Systems technology. The main features and capabilities of navigation systems such as Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), BeiDou Navigation Satellite System (BDS), GALIEO Satellite Navigation System are presented. Various possibilities for the use of Global Navigation Satellite Systems in agriculture are considered: precision farming, GIS, Soil sampling, Field mapping, Remote sensing, Yield monitoring, VRT, etc. The course presents the principles underlying the use of GNSS at meter and sub-meter accuracy for applications in surveying, GIS, agriculture, asset management, and scientific studies. The student will learn the basics of navigation using Global Navigation Satellite Systems (GNSS), such as GPS signals, and other navigation technologies. The student will also get a practical training on the GNSS receiver functionalities via a course work assignment. |
