2. Objectives and learning outcomes
2.1 Objectives
The course aims to introduce the operational background of the global navigation satellite systems (GNSS), to discuss the mathematical models, systematic error sources and the standaridzed data formats of satellite positioning. The students gain extensive knowledge on the applications of GNSS positioning in geodesy, geomatics, civil engineering navigation, precision agriculture, geodynamics, meteorology, hydrology). The course enables students to process GNSS obsrvations for navigation as well as highly accurate positioning and to analyse GNSS observations and results to obtain valuable information for Earth observation.
