The TGO carries a payload of four instruments in order to reach its scientific goals, including the Colour and Stereo Surface Imaging System (CaSSIS). CaSSIS is a colour and stereo telescopic camera that will be capable of taking high-resolution images of the martian surface. Before shipment of the instrument for integration onto the TGO, a detailed calibration campaign was performed, and a number of calibration products were gathered and utilised as part of the in-flight calibration campaign. This paper presents the results of on-ground calibration measurements carried out in order to assess the pre-flight performance of CaSSIS. All indications are that CaSSIS will perform very well on arrival at Mars and will be successful in reaching its scientific objectives.STAMPAenArticle10.1007/s11214-017-0404-22-s2.0-85031103181000414314200026https://link.springer.com/article/10.1007%2Fs11214-017-0404-22017SSRv..212.1871RFIS/05 - ASTRONOMIA E ASTROFISICA
