Learning objective
After this course, the students should be able to
• Describe the major observation techniques in space geodesy • Describe the necessary modeling and analysis approaches to derive geodetic products of highest quality • Select the appropriate space geodetic data for scientific investigations • Analyze the space geodetic data for scientific purposes • Interpret the scientific results
Content
Overview of GNSS, Very Long Baseline Interferometry (VLBI), Satellite and Lunar Laser Ranging (SLR/LLR), Satellite Radar Altimetry with the basic principles, the instruments and observation equations.
Modelling of the station motions and the estimation of station coordinates. Basics of wave propagation in the atmosphere. Signal propagation in the ionosphere and troposphere for the different observation techniques and the determination of atmospheric parameters.

Performance assessment
Performance assessment information (valid until the course unit is held again)
The performance assessment is offered every session. Repetition possible without re-enrolling for the course unit.
Mode of examination
oral 30 minutes
Additional information on mode of examination
The oral exam can also be carried out in German. A project work carried out by the students will be graded and count as compulsory performance assessment 30% of the final mark.
This information can be updated until the beginning of the semester; information on the examination timetable is binding.
