Course contents :
|
| The course studies the main concepts and measurement techniques used in geodesy and in Geodetic astronomy.
It is organized in 5 chapters :
1. Basics of Geodesy : history, geoid and reference ellipsoid, deflection of vertical, different types of reference systems used in Geodesy.
2. Geodetic astronomy : celestial sphere, astronomical coordinates and their determination, precession and nutations, time scales (sidereal time, solar time, atomic time).
3. Classical Geodesy : reference systems in planimetry (triangulation and its verification, definition of a local datum), reference systems in altimetry (different types of heights, leveling, orthometric correction).
4. Space Geodesy : basics, Doppler method (DORIS, TRANSIT), Satellite Laser Ranging, Very Long Baseline Interferometry, Satellite Altimetry (Topex /Posseidon, Jason), introduction to GNSS.
5. Dynamical Geodesy : terrestrial gravitational field, Geoid and its determination, gravimetry and Gravimetric anomalies. |

Learning outcomes of the course :
|
| The course gives an introduction to the main concepts used in Positional Astronomy and in Geodesy. The student will be able to define correctly these concepts, to explain the links between these concepts and to use them to solve practical problems encountered in Geometrology. An important part of the course is dedicated to Space Geodesy. The course highlights the added value of space techniques in Geodesy. The student will be able to compare the different techniques used in Space Geodesy, their main advantages, disadvantages and complementarities. |
