1S 2012 - GPS - SVT Lyon et Nasa - Vitesses globales - Global Velocities

Des activités "GPS" dans le cadre de la reconstitution de l'histoire de la tectonique des plaques - Voir successivement les deux sites pour travailler sur les vitesses globales de déplacement de stations, donc de plaques tectoniques. Merci aux auteurs pour leurs aides. http://www2.ac-lyon.fr/enseigne/biologie/spip.php?article179 http://sideshow.jpl.nasa.gov/mbh/series.html The Global Positioning System (GPS) is a constellation of 30 satellites which is used for navigation and precise geodetic position measurements. Data from over 2000 recievers have been analyzed at the Jet Propulsion Laboratory, California Institute of Technology under contract with the National Aeronautics and Space Administration. Horizontal velocities, mostly due to motion of the Earth's tectonic plates, are represented on the map by lines extending from each site.
