2. Objectives and learning outcomes
2.1 Objectives
Physical and Theoretical Geodesy is the science of the figure of the Earth, which studies the large-scale figure and gravity field of the Earth, which are closely related. The figure of the Earth is approximated by an ellipsoid of revolution, after which the precise figure is described by small deviations from this ellipsoid. Vertical reference systems are discussed in this context. Extending the approach to the Earth’s gravity field yields small difference quantities, such as the disturbing potential and gravity anomalies. This course covers such modern techniques that were not covered in the previous BSc and MSc geodesy and physical geodesy courses due to lack of time.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
- Is familiar with the terminology of physical geodesy
- Understands the relationship and interdependence of physical geodesy and gravimetry
- Knows the most important mathematical methods in geosciences
- Acquires the modern views on the determination of figure of the Earth
- Recognises the importance of gravity gradients data in physical geodesy
- Learn about QDaedalus measurements
- Knows the possibilities of the determination of fine structure of geoid anomalies
- Understands the problem of geodynamic interpretation of repeated geodetic and gravity observations
- Knows the time variations of geoid and heights
B. Skills
- Is able to understand the relationship between physical geodesy and gravimetry
- Is able to determine the fine structure of geoid
C. Attitudes
- Considers importance attending lectures and continuous mid-year learning
- Cooperates with the lecturer and fellow students in expanding the knowledge
- In addition to the compulsory curriculum, it expands its knowledge through continuous acquisition of knowledge
D. Autonomy and Responsibility
- Independently investigates problems raised in lectures
- Carry out his studies with appropriate responsibility
- Assists fellow students in preparation in necessary situations
