Satellite Design
The COSMO-SkyMed Second Generation (CSG) spacecraft are three-axis stabilised, consisting of the main body (bus), two deployable solar arrays, and a SAR antenna.
The SAR instrument operates in the X-band, 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, 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.
