The main missions of the VIGISAT station operated by CLS are to:

• deliver satellite radar images;
   
• provide near real time services in the fields of environmental monitoring, sustainable management of marine resources, maritime safety and other terrestrial applications;
   
• assist the French and European authorities in their day-to-day state operations at sea.

The acquisition area for near real time satellite images has a radius of 2500 km centered on Brest (from Greenland to the Canaries and stretching from the Azores in the west to the Black Sea in the east).

VIGISAT was set up by CLS as a key part of its operational infrastructure.
