Geodetic methods and techniques in Earth observation

Specialization / Direction

Upon successful completion of the course, students will have developed a solid understanding of how space geodetic techniques are applied to observe, measure, and analyze dynamic processes of the Earth system. They will be able to critically assess various observation methods, interpret geodetic data, and understand their significance in the context of Earth system science. The course will enable students to integrate geodetic observations into broader geophysical analyses, preparing them to contribute to research and practical applications in areas such as crustal deformation, sea level change, Earth rotation, etc. Emphasis is placed on the ability to apply theoretical knowledge to real-world datasets and scenarios, fostering both technical proficiency and scientific insight. In brief, the aim is to provide students with the following competencies at the completion of the course: • Understand the principles of key space geodetic techniques (e.g., GNSS, SLR, VLBI, InSAR, GRACE). • Recognize Earth system processes which are observable through geodetic methods (e.g., tectonics, sea level, Earth rotation). • Analyze and interpret geodetic data to extract geophysical insights. • Evaluate the strengths and limitations of different space geodetic techniques. • Apply geodetic observations in modeling Earth dynamics and deformation.

This course explores the use of advanced space geodetic techniques for observing and analyzing the dynamic Earth system. Building upon students’ foundational knowledge in geodesy and space-based geodetic observations, it focuses on the interpretation of geometric and physical changes of our planet — such as crustal displacements, time-variable gravity field, sea level change, and height changes. The course emphasizes the integration of multiple space geodetic techniques—including GNSS, SLR, VLBI, DORIS, InSAR, and satellite gravimetry—to investigate the geophysical processes underlying these changes. A key component of the course is the presentation and analysis of representative case studies, which demonstrate real-world applications of geodetic observations in monitoring tectonic motion, glacial mass balance, sea level trends, and Earth rotation. These case studies help bridge theory and practice, enhancing students’ ability to critically assess data and synthesize multi-technique results in both regional and global contexts.
