SAOCOM (SAtélite Argentino de Observación COn Microondas, Spanish for Argentine Microwaves Observation Satellite) is a planned Earth observation satellite constellation of the Argentine Space Agency CONAE.


Two satellites are planned, SAOCOM 1A and SAOCOM 1B. Both will be equipped with a L-band (about 1275 GHz) full polarimetric Synthetic Aperture Radar (SAR). Each weighs 1600 kg[1] and their main purpose will be monitoring for the prevention of disasters.


Originally launch was announced for 2010 (1A) and 2011 (1B),[2] but later due to delays in satellites' development both launches were postponed to between 2012 and 2013.[3] Further delays pushed the launches date back tentatively towards 2014 and 2015 respectively for 1A and 1B satellites.[4] Falcon-9 rockets will be used for the launches.[5]

Those two satellites along with four X-band (around 9.6GHz) SAR equipped COSMO-SkyMed satellites from the Italian Space Agency ASI would form the Italian-Argentine System of Satellites for Emergency Management (SIASGE) constellation.[6] A successful design review was held at the Teófilo Tabanera space center in Cordoba on 16 and 17 October 2012. In May of 2015 a delegation from from the Italian Space Agency visited Argentina. CONAE officials announced that discussions between the two agencies included the expansion of the of the SIAGSE system by adding two additional COSMO-SkyMed satellites and two additional SAOCOM satellites, 2A and 2B. This would raise the SIAGSE constellation total number of satellites to 10.
