Entry knowledge

Fundamental principles of geophysics, astronomy and gravitational theory at the level of bachelor´s and master´s degree.

Rules for evaluation and completion of the course

Verification of knowledge and skills takes place in exercises. Students are motivated to continuous study even during the lessons. The teacher repeatedly emphasizes essential profile information. The exam is carried out in the form of a test as well as in writing. Evaluation is carried out according to valid principles with a set scale of evaluation.


Extent and forms are specified by guarantor’s regulation updated for every academic year.
