Mission organization during the exploitation phase

The technical part of CoRoT mission exploitation is mainly composed of operational activities (monitoring and instrument and satellite et programming), processing activities and data production for the scientific community as well as maintenance activities. All the technical activities lean on a project like organization under CNES general responsibility, with a high involvment of INSU laboratories and in an international cooperation framework.

Beyond this, the collection of the stellar fields characteristics data, the scientific analysis of the data supplied by the satellite after processing and the additional observation programmes from the ground are realized by the scientific community. The observation programme choice and the coordination of CoRoT scientific teams (Stellar sismology teams, Exoplanet programme teams, additional programmes team, ground observation teams) are realized by CoRoT Scientific Committee, which also defines the data distribution and scientific publications policy.

National level

The CoRoT satellite operations, the instrument programming and monitoring activities, the alarm level L0 and L1 data production are realized in the CoRoT Control Center (CCC) and CoRoT Mission Center (CMC) located in Toulouse (see page "Ground Segment").

The data management, particularly the stellar catalogues, the level L2 data production and distribution are realized by the CoRoT Data Center (CDC). This center is divieded between several INSU (Institut National des Sciences de l'Univers) laboratories: the IAS (Institut d'Astrophysique Spatiale) in Orsay, the LAM (Laboratoire d'Astrophysique de Marseille), the LATT (Laboratoire d'Astrophysique Toulouse Tarbes) and the LESIA (Laboratoire d'Etudes Spatiales et d'Instrumentation en Astrophysique).

The instrument technical expertise is under LESIA's responsibility.

International level

The mission exploitation is realized in an international cooperation framework. Germany (maintenance of the instrument DPU software), Austria (BEX electronics box expertise and reception station in Vienna as back-up), Belgium (stray light expertise), Spain (CMC softwares maintenance), Brazil (ALCANTARA station operation for the PLMT2 instrument data reception) and ESA (DPU electronics expertise), each bring his technical contribution. These different protagonists are also highly involved in CoRoT scientific programme.
