CFOSAT is a French-Chinese mission embedding two wave and wind measuring instruments. Its launched is schedule for 2015. The CERSAT is deeply involved in this project, both providing scientific expertise and hosting the future wind & wave data processing and archiving center for this mission.


cfosat-logoCFOSAT (Chinese-French Oceanic SATellite) is developed jointly by CNES for France and the Chinese National Space Agency (CNSA). It will be dedicated to the remote sensing of ocean surface winds and waves, through two embedded instruments :

  • SWIM (Surface Waves Investigation and Monitoring) is a rotating radar, operating in Ku band, able to measure both swell wave length and direction over a 70 km large swath. It is provided by CNES and built by Thales Alenia.
  • SCAT is a rotating scatterometer also operating in Ku band. It is developed by China.

CFOSAT satellite is built by China and will be launched by a Long March 2C rocket in 2015. The expected nominal duration of the mission is 3 years.


The CERSAT brings a major contribution to the mission :

  • we are part of the scientific mission group, bringing expertise and supporting the development of the processing chains for both SWIM and SCAT instruments, and contributing to the cal/val
  • we will be a component of the ground segment, developing and operating a dedicated data processing and archiving center, delivering :
    • swath (level 2) wind and wave products in a 24h delay
    • multi-sensor wave and wind fields combining both instruments and other sources of measurements
    • quality assessment and monitoring of the sensor geophysical performances
    • usage in applications such as wave forecasting
