This paper provides the main outcomes from studies dedicated to the Visible and Infrared Radiometer (VIRI) for Meteosat Second Generation (MSG) geosynchronous satellite to be launched in 1995. These studies are performed by MATRA Space Branch with the collaboration of TPD (NL), Marconi (UK), BAe (UK) and Aerospatiale (F) and supported by European Space Agency (ESA) and Centre National d'Etudes Spatiales (CNES). The objective of MSG is to ameliorate the service already offered by the operational Meteosat serie in order to fit the rapid development of high resolution numerical weather prediction models. This is reflected in the requirements for VIRI which can be regarded as very ambitious as calling for simultaneous improvements in spatial, spectral, temporal and radiometric resolutions. Associated with those are stringent requirements on channel registration and the need to implement a really efficient on-board calibration. The instrument feasibility is primarily dictated by the spatial resolution, from which are derived the aperture diameter and the number of detectors. The preferred instrument concept is described with particular attention to the optical, radiometric and calibration aspects and to the infrared' detection cooling technique.
