Despite all four satellites are beyond the end of their lifetime, all the performances are fully preserved. This is possible also thanks to a continuous and careful control of the entire system. Moreover, in order to face market competition and to fulfill customers' needs, a process for the implementation of improved SAR Spotlight modes inside COSMO-SkyMed system has been put in place. This paper technically traces the natural evolution of the system from COSMO-SkyMed (CSK) toward COSMO Seconda Generazione (CSG) through an intermediate step characterized by an experimentation phase possible thanks to the high flexibility of CSK project and design. © VDE VERLAG GMBH · Berlin · Offenbach.Synthetic aperture radarconference paperhttps://www.scopus.com/inward/record.uri?eid=2-s2.0-85000885323&partnerID=40&md5=501035a5add9c912d755c637f94ebbc2
