Overview

• The COSMO‐SkyMed Constellation• Contributions to DWH Phase 2 DAPs• Service enhancements for DWH Phase 2

Thank you for your attention !The COSMO-SkyMed Constellation

The COSMO‐SkyMed Constellation in brief

• Owned by the Italian Space Agency (ASI) and IT‐MOD – operated by Telespazio and e‐GEOS

• Constellation of 4 identical SAR satellites– Highest revisit– Best response time– High imaging capacity all over the world– 4 interferometric acquisitions every 16 days

Unmatched Revisit

• At least 4 acquisitions / day (@ equator):

– 1 left looking and 1 right looking early morning (ASCENDING, approx. 6 AM local time)

– 1 left looking and 1 right looking late afternoon (DESCENDING , approx. 6 PM local time)

COSMO-SkyMed 2nd Generation

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.

• COSMO‐SkyMed constellation is fully deployed and operational • CSG satellites will replace the CSK satellites that reached the end of life• With the launch of the first CSG satellite planned in 2017 and the second one year later, 

CSG will provide operational continuity at least until 2023

COSMO 2nd Generation

The COSMO‐SkyMed Constellation 

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 AD engagements in international cooperation, either civilian or defense (MUSIS), 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
