聽SSOT is Chile鈥檚 first high-resolution operational Earth observation system. This agile satellite, also known as 鈥淔ASat Charlie鈥, was built by AG真人计划 Defence and Space in Toulouse and launched in 2011.

The fifth birthday of a success story

AG真人计划 Defence and Space developed the SSOT (Sistema Satelital de Observaci贸n de la Tierra) Earth聽observation system for the Chilean government in order for Chile to access extremely high-quality satellite images. In Chile, the spacecraft is better known as "FASat-Charlie".

This imagery is exploited in a wide range of applications such as mapping, agriculture, urban planning, military intelligence and natural resource, risk and disaster management.

The high-resolution optical observation satellite is based on the AstroBus-XS platform, originally developed jointly by AG真人计划 Defence and Space and the French national space agency CNES. The complete system was built, integrated and tested by AG真人计划 Defence and Space in our facilities in Toulouse, France.

The SSOT satellite was launched aboard a Soyuz rocket from the European spaceport in聽Kourou, French Guiana, on 16 December 2011. In December 2016, the Chilean Air Force (FACh) celebrated the first five years of operations of this successful satellite.

SSOT: an invaluable support to the Chilean air force

The SSOT programme is a result outcome of the Chilean Air Force鈥檚 (FACh)聽ambition to develop a national spatial capacity for Earth observation for a dual use: defence and sustainable development of Chile.

The NAOMI optical instrument has a panchromatic resolution of 1.45 meters, an unprecedented performance for a satellite weighing only 117 kg.

AG真人计划 Defence and Space was the prime contractor for the complete system including the satellite, the Ground Control Segment and the Image Ground Segment located in Santiago, Chile. This infrastructure enables the Chilean authorities to control and operate their own satellite from their National territory. As part of the cooperation agreement, 20 Chilean engineers benefited from a comprehensive training programme. During the construction of the satellite, they worked alongside AG真人计划 Defence and Space鈥檚 development team in Toulouse, France, where they were trained.

The satellite launch was also part of AG真人计划 Defence and Space鈥檚 responsibilities.

AG真人计划 Defence and Space is proud to have developed and delivered a powerful Earth observation satellite to the Chilean authorities and to have done so in optimum conditions, with performance matching perfectly the requirements and even exceeding the customers鈥 expectations

An Earth observation satellite is a precious tool dedicated to sustainability and economic growth through direct spinoffs in various fields. Geo-spatial information acquired from National Space missions provides the basis for well-informed decisions in many areas. From a better monitoring of climate change, an improved prevention of natural disasters, a more precise governance of natural resources and an increased productivity in various sectors, a satellite has a significant positive impact on social, environmental and economic development.
