Research activities within SIASGE programme (2011/2013)
SIASGE (Italian-Argentine Satellite System for Emergency Management) is a joint programme of the Italian Space Agency and the Argentine Space Agency CONAE (Comision Nacional de Actividades Espaciales) which includes the integration of two satellite constellations for Earth Observation: COSMO-SkyMed and SAOCOM.
Cosmo SkyMed is the most ambitious programme of Earth Observation satellite ever realized by Italy for prevention of
environmental disasters, Earth surface study and security.
Developed by the Italian Space Agency in cooperation with the Italian Ministry of Defence, Cosmo SkyMed consists in a constellation of four identical satellites, equipped with X-band Synthetic Aperture Radars (able to scan the Earth from space, day and night in all weather conditions). Once completed, the system will be able to carry out up to 450 radar shots a day of the Earth surface, amounted to 1,800 radar images every 24 hours.
SAOCOM constellation (SAtélite Argentino de Observación COn Microondas) of the Argentine Space Agency is formed by two
satellites equipped with L-band Synthetic Aperture Radar, whose launch is planned from the end of 2014.
The SAR (Synthetic Aperture Radar) is a radar system, it illuminates the Earth by microwaves allowing accurate observation of vast areas. Onboard aerospace platforms it can penetrate vegetation and the first subsoil layers, with an high resolution of the selected area, in any weather condition, either during the day and during the night. The multi-frequency data obtained are used, among other things, to study and better understand global environment and its changes. Therefore they are employed for natural disasters prediction and prevention, cultivation management and forest classification, estimate of quantitative parameters, as biomass and soil humidity, monitoring of glaciers, sea pollution and areas subject to flooding.
Within this programme CO.RI.S.T.A. participated in the research activities concerning the SAR payload for the Critical Design Review of the SAR instrument. The activities, in the form of scientific support, have been held at CONAE headquarters in Buenos Aires, Argentine, closely with CONAE team of researchers. A first phase, which started in 2011 and ended in June 2012, was carried out on behalf of Thales Alenia Space Italia, while CO.RI.S.T.A., since July 2012, was charged directly by the Argentine Space Agency CONAE to carry on the activities which ended in October 2013.
