Clone of COSMO-SkyMed Second Generation 2 (CSG-2)

OSMO-SkyMed Second Generation (CSG) is at the forefront of radar technology, and will ensure improvements and guarantee continuity with the First Generation COSMO-SkyMed (CSK) satellites, preserving the high quality and the highest precision features, both required for the interferometric activities.

The programme is funded by Agenzia Spaziale Italiana (ASI), the Italian Ministry of Defence and the Italian Ministry of Education, Universities and Scientific Research.

As with the four first-generation satellites, the second-generation satellites are defined as a dual system (civil and military).

COSMO-SkyMed Second Generation consists of two enhanced SAR satellites:

  • CSG-1, the first satellite of the COSMO-SkyMed Second Generation, successfully launched on 18 December 2019 from Kourou Space Center (French Guiana) using a Soyuz launcher
  • CSG-2, the second satellite, successfully launched on 31 January 2022 from Cape Canaveral (USA) on Falcon 9.

Objectives

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 fulfil their mandates.

CSG represents a step ahead to bring the best advantages of the space observation to the largest number of people, to improve the integrity of the environment, quality of life, safety and security.

COSMO-SkyMed Second Generation's purpose is to monitor the Earth for the sake of emergency prevention, strategy, scientific and commercial purposes, providing data on a global scale to support a variety of applications among which risk management, cartography, forest & environment protection, natural resources exploration, land management, defense and security, maritime surveillance, food & agriculture management.
