Satelital

Brindamos cobertura satelital en todo el continente americano.

Through our geostationary satellites ARSAT-1 and ARSAT-2, we offer coverage in Argentina and the entire American continent, including Antarctica and the Malvinas Islands. They perform successfully with an occupancy rate of more than 90%. A third satellite will be added to the fleet, ARSAT-SG1, will be electrically propelled and will become the first national HTS satellite to work in Ka-band.

The International Telecommunication Union (I.T.U) is the United Nations agency in charge of establishing the criteria for the assignment of orbital positions, proceeding with their allocation and verifying their efficient use. Since geostationary orbital positions are a very valuable and extremely scarce strategic resource, countries that are assigned an orbital position run the risk of losing it if they do not occupy and exploit it within three years. Argentina is currently using two orbital positions: 72° and 81° West longitude.

During the 1990s, the orbital positions had remained in the hands of a foreign capital company, Nahuelsat, which some years later was about to default on its obligation to put a satellite in orbit at position 81⁰ West. Many countries pretended the position assigned to Argentina, but the most remarkable case was that of the United Kingdom. Fortunately, Argentina’s representations to the I.T.U were successful and it was possible to keep the position 81° West longitude, which has been part of our heritage since 2006. Since 2015, ARSAT-2 has provided services in that orbital position.

On the other hand, the Nahuel 1A satellite, which the same company used to provide services from the geostationary position 72⁰ West, which was approaching the end of its useful life, accumulated several propulsion thruster failures. The Nahuelsat company decided not to replace it, which again endangered an orbital position assigned to Argentina.

In August 2007 amajor failure of Nahuel-1’s propulsion system occurred. To deal with this problem, Nahuelsat’s team of satellite engineers developed a manual orbit and orientation control procedure to keep Nahuel-1’s clients and allow a controlled migration to another adjacent satellite (AMC-6, also in the orbital position 72° West longitude).

Again in defence of the orbital positions assigned to Argentina, in 2007 the government terminated the contract that had been signed with this company in the early 1990s and ordered the transfer of its assets to the national government, which remained under our responsibility. Among them, one of capital importance: the position 72° West longitude. Since 2014, ARSAT-1 has been providing services in that orbital position.

Our satellites

Our satellites work successfully with an occupancy rate of 90% and export more than 30% of their services.
