| The goal | ||||
| Introducing students to the possibilities of using Earth's artificial satellites to solve basic geodetic tasks of positioning, determining the gravity field and geodynamics. | ||||
| The outcome | ||||
| Students will be introduced to the basic theory of satellite motion and the types of satellite measurements that can be used for positioning, gravity field determination, and geodynamic research. The acquired knowledge will enable students to more easily master the capabilities of satellite systems and techniques used in geodesy, with a focus on the widely used NAVSTAR GPS satellite system. | ||||
