Argentine operator Arsat revives plans for third satellite

WASHINGTON — Argentina’s nationwide satellite tv for pc operator Arsat, undeterred by the rising coronavirus pandemic, expects to quickly signal a contract with home producer INVAP for a geostationary communications satellite tv for pc.

Arsat, which has two satellites in orbit, had signed a contract with Arianespace to launch a 3rd satellite tv for pc in 2019 on an Ariane 5, however that satellite tv for pc was by no means constructed. 

In an interview final week on the Satellite tv for pc 2020 convention right here, Arsat CEO Pablo Tognetti stated the brand new Argentine authorities established in December has determined to finance a 3rd satellite tv for pc, reversing a choice from the earlier administration. Arsat hopes to launch its third satellite tv for pc in 2023, he stated. 

Martin Fabris, Arsat’s house division supervisor, stated by e-mail March 18 that the contract signing will doubtless take a couple of month to shut, partly due to the coronavirus pandemic, throughout which about 80% of Arsat staff are working remotely. 

Argentina has reported 65 coronavirus instances and two deaths as of March 18, based on the World Well being Group. The nation has a comparatively small share of the reported coronavirus instances throughout the American continents, which WHO numbered at 4,979 confirmed and 68 deaths. 

Arsat’s  has renamed its deliberate third satellite tv for pc, previously known as  from Arsat-3, to has been renamed SG-1, brief for Second Technology-1, Tognetti stated. The title change displays a shift to high-throughput Ka-band capability, all-electric propulsion and an elevated use of Argentine subsystems, he stated. 

“We took benefit of that delay to go and begin this new technology,” he stated. 

Whereas the delay produced some manufacturing advantages, it additionally launched launch difficulties. Arianespace is phasing out the Ariane 5 rocket that Arsat contracted in favor of the next-generation Ariane 6, which has a primary flight towards the top of this 12 months. 

The final Ariane 5 launch is anticipated by 2022 on the newest, however SG-1 received’t be prepared till 2023. Tognetti stated Arsat is reviewing autos and can doubtless recompete the SG-1 launch. 

SG-1 will present broadband connectivity to varsities, hospitals and rural residents past the attain of Arsat’s 30,000 kilometers of fiber optic cables, Tognetti stated. 

Fabris stated SG-1 may have a minimum of 50 gigabits per second of complete capability overlaying Argentina and neighboring international locations. The satellite tv for pc will probably be a small GEO weighing simply over 1,000 kilograms, with a design lifetime of 15 years and a payload energy of seven kilowatts, he stated. 

The satellite tv for pc’s unique design referred to as for a chemical propulsion system, Fabris stated. The delay gave INVAP time to develop an electrical propulsion system, plus different parts that have been ordered for earlier satellites, based on Tognetti. 

Arsat is sure by Argentine regulation to obtain satellites solely from Argentine producers, Tognetti stated, making state-owned INVAP the de facto provider. 

INVAP constructed the Arsat-1 and Arsat-2 satellites. Every weighed roughly 3,000 kilograms and launched on Ariane 5 rockets, Arsat-1 in 2014 and Arsat-2 in 2015.
