2. Objectives and learning outcomes
2.1 Objectives
This course aims at conveying up-to-date knowledge on the research and applications of the satellite navigation technologies, especially GNSS and satellite radar imagery in Geosciences, including geophysics, tectonophysics, meteorology, atmospheric sciences and hydrology.
Moreover, the recent developments and advances in satellite navigations are also introduced in the course, including global and regional navigation satellite systems, augmentation systems, ground based radionavigation systems and the fusion of satellite navigation observations with other positioning and attitude determination sensors (e.g INS, barometer, etc.).
