Paris Sud Observatory
The OSU ParisSud is, since 2001, one of the Observatories created by the Ministry of Research and Education after recommendation from the council of the Institut National des Sciences de l'Univers (INSU). It insures services to the community mainly related to the space missions the institute is involved in.
The OSU ParisSud observatory hosts a national facility recognised both by the CNES and INSU: The calibration station. The OSU ParisSud has developed IDOC Integrated Data and Operation Center recognised again by CNES and INSU as well as ESA and NASA.
