Entry knowledge
Knowledge of Cosmic Geodesy 1, knowledge of spherical trigonometry, theory of free nutation.
Rules for evaluation and completion of the course
Students' knowledge is continuously verified in exercises by assigning independently solved problems.
Knowledge at the end of the semester is verified by an exam. It has a written and an oral part. The condition for admission to the oral part is obtaining at least 50% of points in the written part.
Lectures are optional, attendance at excercises is compulsory.
Aims
The aim of the course is to extend the information from Space Geodesy 1, especially in the area of description of the Earth as part of the Universe and description of some other important techniques of space geodesy.
The aim of the course is to expand students' knowledge in the field of space geodesy.
Students will learn, among other things:
- Spherical coordinate systems and transformation between them,
- rotational times,
- the precession-nutation motion of the Earth's axis,
- classical and modern instruments of geodetic astronomy,
- other space geodesy techniques (VLBI, SLR, satellite altimetry, DORIS, satellite gravity missions, InSAR).
In addition, they will get practical experience in determination of astronomical azimuth from measurements at Polaris.
