ARSAT Second Generation 1

Located at the 81°W geostationary position and co-located with ARSAT-2, assigned by the International Telecommunication Union - ITU for its Ka-Band services, ARSAT-SG1 will allow us to defend the orbital position as a scarce asset of high strategic value at an international level, for commercial exploitation during its useful life.

The ARSAT-SG1 satellite

ARSAT-SG1, as well as being the first high throughput satellite, will also become the first national satellite to run a Ka-band payload and will have a traffic capacity of about 70 Gbps, particularly 50 Gbps in Argentina.

We will be able to provide reliable, high-quality satellite broadband in rural areas of low population density where terrestrial infrastructure deployment is not convenient. It is estimated that more than 200 thousand homes in Argentina and neighbouring countries will be reached at affordable prices. In addition, we will be able to expand the networks of mobile communications operators in rural areas as well.

Technological innovation

The new platform will incorporate the main world technological trends in the telecommunications space industry, such as full electric propulsion, both for lifting the satellite from the transfer orbit to the geostationary orbit and for its maintenance at the location from where it operates.

Unlike satellites with traditional capacity, payloads with the new HTS (High Throughput Satellite) technology allow the reuse of frequencies with reduced coverage beams, multiplying the total capacity available in the satellite. ARSAT-SG1 will have more than 40 beams, high spectral efficiency and good signal strength, which will allow greater data transfer. From its geostationary position 81° West, it will cover the entire national territory and the neighbouring countries of Chile, Paraguay and Bolivia.

ARSAT-SG1 will weigh about 2,000 kg at launch, while our first two missions, ARSAT-1 and ARSAT-2, weighed about 3,000 kg, due to the weight of the chemical fuel. The electrical power available for the payload will double that of those satellites. On the other hand, as with the satellites currently in operation, the design lifetime of ARSAT-SG1 will be 15 years.
