| ASTR0213-2 | Geometric Geodesy and Positional Astronomy
 |
|
| Duration : | 25h Th, 5h Pr, 1d FW |
|
| Credits/ECTS : |
|
|
| Holder(s) : | René Warnant |
|
| Language : | French language |
|
| Course contents : | The first part of the course gives a brief introduction to Positional Astronomy :
- Astronomical coordinates and their determination.
- Precession - nutations
- Kepler's laws
- Time scales
The second part is dedicated to Geodesy :
- Geometric Geodesy : triangulation, reference ellipsoid, Datum definition.
- Space Geodesy : Doppler method (DORIS, TRANSIT), Satellite Laser Ranging, Very Long Baseline Interferometry, Satellite Altimetry (Topex /Posseidon, Jason), gradiometry (Grace).
- Introduction to the Global Positioning System (GPS). |
|
| Course objective : | 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 and, in particular, to the Global Positioning System. 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. In addition, the different error sources affecting the techniques used in Space Geodesy are discussed. |
