COSMO-SkyMed (COnstellation of small Satellites for the Mediterranean basin Observation) is a constellation of 4 Synthetic Aperture Radar (SAR) imagery satellites conducted by the Italian Space Agency for civil and military use. Its main applications are maritime awareness, defense and intelligence, thematic mapping, emergency response, and land stability analysis. The constellation was launched over 3.5 years beginning June 2007 with the final satellite launching in November 2010. The number of satellites in conjunction with the use of a SAR sensor allows for observations of an area of interest to be repeated several times a day in all-weather conditions. The COSMO-SkyMed satellites have three basic types of imaging modes: Spotlight, a high-resolution mode collected over a small area by steering the radar beam slightly fore-to-aft during the collection period. Stripmap, a medium-resolution mode collected over long, continuous swaths in which the beam is pointed broadside to the satellite track. ScanSAR, a low-resolution mode that creates extra-wide swaths by collecting short segments at different ranges and then mosaicking them together.
