Name: Geodetic Reference Frames
Major: Geodesy and Cartography
Study Type: first cycle
Course type: compulsory
Study Semester: 4
ECTS points: 6
Hours (Lectures / Tutorials / Other): 30 / 30 / 0
Lecturer: dr Krzysztof Sośnica
Language of instruction: Polish / English
The course in English will be available if a minimum of 6 students sign up for a group. If fewer than 6 students sign up for the group, the course will be available in Polish with the possibility of individual support in English.
Learning outcomes: Students should acquire theoretical and practical knowledge related to geodetic reference systems and their realizations. In particular students should know the relationships between reference systems: International Celestial Reference System (ICRS), global International Terrestrial Reference System (ITRS), and regional European Terrestrial Reference System 89 (ETRS89). Students should know the theoretical principles of the realization of reference frames using techniques of satellite and space geodesy. Students should acquire theoretical and practical knowledge related to realization of the geodetic reference frames through control points in geodetic networks. Students should be able to solve the basic tasks of geodetic positioning on the physical surface of the Earth as well as to calculate a transformation between various realizations of the geodetic datum. In particular, knowledge of the geometry of the sphere and ellipsoid and geodetic astronomy is expected. Students should be able to plan, measure high-order horizontal networks referred to the earth ellipsoid as well as levelling networks referred to the geoid (quasigeoid). Students should know the fundamentals related to Earth rotation such as precession, nutation, polar motion, excess of length-of-day, UT1-UTC. Students should become familiar with the International Earth Rotation Service (IERS) Conventions.
Competences: Completion of the course provides ability for continuing education in the field of Global Navigation Satellite Systems (GNSS) and the skills of measurements of high-order geodetic networks and their development.
Prerequisites: mathematics, physics, adjustment theory, geodetic surveying I and II
