The ORFEO programme (Optical and Radar Federated Earth Observation) was an agreement between France and Italy about coordinating Earth observation satellites development and use. The countries agreed to implement co-operation for setting up an Earth observation capability using optical and radar sensors, and to define the context in which the dual-purpose system (military and civilian) was to be developed and used. It was composed of 6 high-resolution satellites: 4 COSMO-SkyMed X-band satellites from Italy, and 2 Pléiades optical satellites from France.
