COSMO-SkyMed SG Overview
Satellite Design
COSMO-SkyMed Second Generation (CSG) spacecraft is three-axis stabilised, consisting of the main body (bus), two deployable solar arrays, and a SAR antenna.
SAR instrument operating in the X-band operates in different imaging modes with Single or Dual polarization satisfying different needs.

Mission Operations
The two CSG satellites are placed on the same orbit as the first generation COSMO-SkyMed (CSK) satellites, therefore guaranteeing additional imaging opportunities at the same dusk/dawn orbit (6:00 AM local time ascending passes, 6:00 PM local time descending passes) and additional interferometric revisit in the 16 days cycle.
The satellites are phased in the same orbital plane, with COSMO-SkyMed-2, 3 and 1 at 90° to each other, COSMO-SkyMed-4 at 67.5° from COSMO-SkyMed-2, CSG-1 at 45° from COSMO-SkyMed-1. The position of CSG-2, as currently defined by ASI and I-MoD (Italian Ministry of Defence) is at 180° from CSG-1.
The ground segment of the system is composed of a command centre in Italy with tracking and data downlink stations in Argentina and Sweden.
