About COSMO-SkyMed Second Generation

COSMO-SkyMed Second Generation

COSMO-SkyMed Second Generation 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, should be launched in 2021

CSG mission parameters:

Launch dates CSG-1: 18 December 2019
CSG-2: 2021
Orbit Height 619.6 km
Orbit Type Sun-synchronous polar orbit
Nominal Local Time at Ascending Node 06:00 AM
Orbit Inclination 97.87°
Orbit Period 97.2 minutes
Repeat cycle 16 days

 

COSMO-SkyMed Second Generation is part of ESA's Third Party Missions Programme, in which ESA has an agreement with ASI to distribute data products from the mission.

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 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.

Data

DATA DESCRIPTION

For scientific research and application development (both archived and new acquisitions), the COSMO-SkyMed Second Generation data are available for free following the approval of a project proposal. ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project.

DATA TOOLS

A number of tools are available for visualising, processing and analysing COSMO-SkyMed SG data.

PolSARpro

PolSARpro (Polarimetric SAR data Processing and Education) supports the scientific exploitation of polarimetric SAR data and is a tool for high-level education in radar polarimetry.
