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 1.275 GHz) full polarimetric Synthetic Aperture Radar (SAR). Each weighing 1,600 kg (3,500 lb)[1] and their main purpose will be monitoring for the mitigation of natural disasters effects.


Originally, the launch was announced for 2010 (1A) and 2011 (1B),[2] but later due to delays in satellites development both launches were postponed for 2012 and 2013.[3] Further delays pushed the launches date back tentatively towards 2014 and 2015.[4] As of February 2016, SAOCOM 1A was later scheduled for launch in December 2016[5] and SAOCOM 1B in December 2017.[6] As of April 2016 the scheduled launch dates for 1A and 1B were further pushed back to October[citation needed] 2017 and October[citation needed] 2018.[7] Falcon-9 rockets will be used for the launches.[8]

SIASGE Constellation[edit]

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.[9] A successful design review was held at the Argentinian space centre Teófilo Tabanera near the Cordoba City 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.
