How do you locate the Vendée Globe skippers, the key information for the ranking ? How do you secure the race by detecting the most threatening icebergs?

[DIRECT #VG2016]​ Meeting on December 14, starting at 4:30 pm

To answer these questions, We must rise thousands of kilometers in space, aboard the satellites used by CLS, a subsidiary of CNES, the French spatial agency. Follow this Live show, animated by the teams of the Vendée Globe, who will give to experts the opportunity to explain the observed situations since the beginning of the race !

A race located by satellites.

Throughout the race, the skippers are followed by satellite thanks to CLS. Each boat is equipped with "MAR YI" location and assistance tags. The satellite tags regularly send a message to locate the boat. Thanks to this location, the racing PC can establish the classification, provide a map to the public but also improve the safety of skippers at sea.

Each Vendée Globe skipper is equipped with MAR-YI tracking tags developed by CLS.

Threatening icebergs detected from space.


CLS provides its expertise in satellite data processing with radar imagery, altimetry data (sea level measurement) and ocean currents models to detect the presence and predict iceberg drifts all around Antarctica.

Over the last two editions, several dozens of icebergs, which could threaten the skippers, were detected by CLS.


H24 Space Operations Centers based in Toulouse and Brest​.

CLS best teams are working for the Vendee Globe race. From Toulouse and its operations center, it collects data from nearly 130 satellites. They help localize skippers in real time, collect sea conditions (temperature, currents, etc.) and key information to predict the iceberg drifts. From Brest and its VIGISAT radar station, CLS acquire high-resolution radar satellite images and data analysts detect icebergs with predictive algorithms for the safety of skippers.
