Courses at Chair of Physical Geodesy and Satellite Geodesy (PSG)

 

Range of Courses

The PSG offers courses in the following study programs:

The main courses by PSG in the study programs are Physical Geodesy, Reference Systems and Satellite Geodesy. In addition the institute is responsible for lectures and exercises in Adjustment Theory, Parameter Estimation and Signal Processing in their context to Geodesy.

In the following the courses are listed together with their contents (by key words). In the course of re-accreditation of both study courses the study programme has been changed to some extend. The following list gives the course structure as valid from winter term 2014/2015 on. Furthermore the teaching staff of PSG contributes to the cross-institute activities like Geodetic Seminar I and II.
