Italy plans second-generation Cosmo SkyMed constellation

As they presented the first images from Italy's first Cosmo SkyMed X-band synthetic aperture radar (SAR)-equipped Earth observation satellite, Italian space agency ASI and the Finmeccanica- and Thales-controlled Telespazio spelled out plans for a second generation of satellites due to replace the four-satellite Cosmo SkyMed constellation after 2014.

The new dual-use constellation - also to be formed of four satellites - is likely to be preceded by a "fifth" first-generation Cosmo SkyMed. This BISSAT, or bistatic satellite, will feature differential interferometry capable of providing provide extremely accurate information, including on moving objects.

Thales Alenia Space studying platforms with sub-metre SAR resolution, multi-encryption for customised access to the data, adjustable narrow-beam downlink and distributed mission management for tactical applications. These second-generation Cosmo satellites would not be limited by international traffic in arms regulations, to allow for a maximum freedom civil use.

First-generation Cosmo SkyMed units offer up to 1m (3ft) resolution for civil use, and classified military performance. The first satellite was launched in June and will be joined by the second on 5 December, the third in mid-2008 and the fourth about a year later.

From February 2008 the first Cosmo SkyMed will offer data to the civil market via e-Geos, a company formed by ASI and Telespazio.

Italy also has reciprocal agreements to share Earth observation data with French (HELIOS II and later Pleiades dual-use satellites) and Argentinian (L-band SAOCOM civil satellites) programmes.

Kenya will receive Cosmo SkyMed data free of charge and participate in a technical training programme for African operators.
