The satellite operator CLS (Collecte Localisation Satellites), a subsidiary of the French Space Agency CNES, IFREMER and the investment company ARDIAN, plays a key role throughout the Vendée Globe race.
The geospatial data of South seas are captured by altimetry and radar imagery satellites,and processed, analyzed by the CLS teams in France. Thanks to the VIGISAT station, these allow to detect the icebergs and to provide the safest routes of navigation to the direction of race of the Vendée Globe. The satellite tags on the ships allow to give information about the navigators position.
Satellites make it possible to establish the safest routes and locate navigators. Soon, they will be able to give information on the size of the waves. The French Space Agency (CNES) and the Chinese Space Agency (CNSA) are collaborating on the CFOSAT program on this way.
