Constellation of Small Satellites for Mediterranean Basin Observation COSMO-SkyMed (CSK) is one of the most advanced and powerful assets in the Earth observation field in which Italy plays a key role at world level. CSK has been designed for dual-use purposes to fulfill both civilian and defense needs, providing useful scientific and commercial applications and strategic monitoring. Since 2008, thanks to its features, the Italian Constellation is able to provide a strong contribution in several application domains such as Geo-hazard Risk Management (seismic events, volcano eruptions, landslides monitoring, and so forth), Ocean and Marine Applications, Land Cover and Vegetation, Polar Research, Cultural Heritage Monitoring, Water Resources and Hydrology. The focus of this article is to analyze the CSK data exploitation to monitor the trend over the last 4 years (2014-2017). Specifically, statistics have been provided based on different acquisition modes, application domains, and the geographic area of interest. The article also highlights the role of the CSK system in the context of international cooperation, focusing on the ongoing partnerships and agreements signed by the Italian Space Agency to facilitate CSK data exploitation.

用于地中海盆地观测的小卫星星座COSMO-SkyMed（CSK）是地球观测领域中最先进，最强大的资产之一，意大利在世界范围内发挥着关键作用。CSK设计用于双重用途，可满足民用和国防需求，提供有用的科学和商业应用以及战略监控。自2008年以来，凭借其功能，意大利星座能够在多个应用领域中做出巨大贡献，例如地质灾害风险管理（地震事件，火山喷发，滑坡监测等），海洋和海洋应用，陆地覆盖和植被，极地研究，文化遗产监测，水资源和水文学。本文的重点是分析CSK数据开发，以监控过去4年（2014-2017年）的趋势。具体而言，已基于不同的采集模式，应用程序域和感兴趣的地理区域提供了统计信息。本文还重点介绍了CSK系统在国际合作中的作用，重点是意大利航天局为促进CSK数据开发而正在签署的现行伙伴关系和协议。
