Learning Outcomes

This module teaches how to describe the gravity field of the Earth and its timely variations. Scientific methods and mathematical concepts for the functional description of gravity related parameters are introduced. After this module the students control scientific methods of different navigation and positioning systems, e.g. celestial navigation, inertial navigation systems, satellite navigation systems, navigation with radio waves, WiFi positioning. Current fields of research and future developments of navigation and positioning are pointed out.
