COSMO-SkyMed Overview

• COSMO-SkyMed is the largest Italian investment in Space Systems for Earth Observation, a National Program conceived by Italian Space Agency (ASI) and funded byItalian Ministry of Research (IMUR) and Italian Ministry of Defence (IMOD)

• It is “natively” conceived as a Dual-Use (Civilian and Defence) end-to-end Earth Observation System

CSG Mission Statement

COSMO-SkyMed Second Generation (CSG) is the

follow-on mission to COSMO-SkyMed (CSK)

assuring continuity and improvement of the supply

of SAR services through data and products, to

preserve and enhance the ability of Customers and

operational Users to fulfill their mandates

Summary

• COSMO-SkyMed is an operational monitoring system based on a number of SAR

satellite missions

• The main driver of the system is ensure continuity and reliability of operational

services

• The constellation guarantees long term Change Detection and very short term Activity

Monitoring

• Integration with SAOCOM will enrich the services provided with multi-band based

information (X & L)

• X-band Second Generation satellites will provide VHR multi-polarization capabilities >

adding target discrimination capabilities

• X-band Very High Resolution provides as well a deeper insight into forest texture

(foliage penetration)

Primary Objectives

• To provide data and service operational continuity to CSK mission with seamless transition

• To supply Earth Observation services through space-borne X-band SAR data and products that will meet the future operational needs of institutional (civilian/defense) users and commercial market

• To support ASI and I-MOD engagements in international cooperation, either civilian or defense, leveraging and improving the existing Interoperability, Expandability and MultiMission/Multisensor capabilities

• To capitalize the heritage of CSK (knowledge, experience, “lessons learned”, assets) and other relevant developments/investments
