Primary ground station
The primary ground station ensures the link on board/on ground with the satellite, or in other words, the transmission of the remote controls to the satellite, the reception of the data from the satellite and the dispatch in real time of the essential surveillance information to the CoRoT control center.
Secondary ground station
The operational ground element is completed by a second ground station located in Brazil. This station is designed to increase the capacity of the link on board/on ground (communications with the satellite) during the calibration and the positioning of the equipment in the station, and to increase the volume capacity of the scientific data during the observation phases.
The validated scientific data is made available via Internet through the project archive located at IAS (Space Astrophysics Institute), Orsay, France. The scientific community associated with CoRoT has private access for one year. In the long term, the data will be forwarded to the Strasbourg Astronomical Data Center.
