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.
The Two satellites, SAOCOM 1A and SAOCOM 1B, both will be equipped with a L-band (about 1275 GHz) full polarimetric Synthetic Aperture Radar (SAR). Each weighing 1,600 kg (3,500 lb) and their main purpose will be monitoring for the prevention of disasters.
Originally, the launch was announced for 2010 (1A) and 2011 (1B), but later due to delays in satellites development both launches were postponed for 2012 and 2013. Further delays pushed the launches date back tentatively towards 2014 and 2015.Currently, the launches are planned for 2016 and 2017. Falcon-9 rockets will be used for the launches.
The two satellites along with four X-band (around 9.6 GHz) SAR equipped COSMO-SkyMed satellites from the Italian Space Agency Agenzia Spaziale Italiana (ASI) would form the Italian-Argentine System of Satellites for Emergency Management (SIASGE) constellation. A successful design review was held at the Argentinian spaceport (Centro Espacial Teófilo Tabanera), Cordoba on 16 and 17 October 2012. In May 2015, a delegation from the Italian Space Agency (ASI) visited Argentina, CONAE officials announced that discussions between the two agencies included the expansion 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.
