  • the first 3 devices to provide internet to the Americas; Coverage in Brazil is expected to begin in the second half.

  • The satellite is expected to operate for about 15 years at a distance of 36,000 km from Earth.

  • In addition to greater internet capacity, ViaSat-3 will have the advantage of directing traffic to where there is greater demand, rather than to a fixed destination.

  • The company wants to increase broadband capacity in Brazil, meeting growing demand from rural areas and the North and Midwest regions.

What is the internet satellite with the highest capacity in the world

Viasat has postponed for the third time the launch of the new Internet satellite with the highest capacity in the world from this evening to Friday (28). a Next attempt will be on Saturday (29)From 20:30.

The satellite reaches speeds of 1 terabyte per second (Tbps), the highest throughput in the world for such equipment.

On Friday (28), it was the launch It was interrupted less than a minute before take-off. In the livestream, the company claimed to be very careful at any sign of something going wrong in flight.

“There are a thousand ways to launch a missile and only one way to make it work,” the presenter said before ending the transmission.

Viasat-3 is a constellation of three satellites that together will bring the Internet to almost anywhere on the planet. This Thursday (27th), the company will attempt to launch its first, ViaSat-3 Americason a SpaceX spacecraft owned by billionaire Elon Musk.

As the name implies, the first satellite to cover the countries of the American continent. The second will cover Europe, the Middle East and Africa, and is expected to be launched in 2023. The third is intended for the Asia-Pacific region, and it does not have an estimated date for sending it into space.

How will the launch be?

According to Viasat, after separating from the rocket, the satellite will deploy its solar panels and then be placed in Earth orbit. After these steps, you can launch the service to consumers.

What changes with the new satellite?

The main novelty is the passing capacity, since Each of the three satellites supports up to 1 terabyte per second. By comparison, ViaSat-2, as of 2017, has about a quarter of that capacity, and can reach 260 gigabits per second (Gbps). ViaSat-1, as of 2011, is up to 140 Gbps.

While ViaSat-3 will cover almost the entire planet, its predecessors will reach smaller areas. ViaSat-2 serves North America, Central America, and the Caribbean, while the first generation is for the United States and Canada.

Another advantage is the possibility Allocate traffic capacity to where there is greater demand, by means of dynamic “packets” (or signal packets). Today, most satellites use fixed “beams”, that is, the amplitude set before launch.

“By using static ‘beams’, you determine in the construction of the satellite where capacity will be allocated and subsequently run the risk of having too much demand and too little capacity in one place, and vice versa,” explains Viasat Brazil’s managing director, Leandro Gaunzser.

“This flexibility of being able to move capacity is a wonderful differentiator.” The packages are “dynamic, so you’ll have capacity where there’s real demand.”

Where will the satellite be used?

Fixed broadband is Viasat’s main business in Brazil, which intends to use the new satellite to increase its mobility in the country and serve places with high demand. According to the company, The greatest demand is in rural areas and in the northern and midwestern regions.

“A large part of the capacity that we will bring to Brazil will be directed to those places where demand is high and, today, less receptive than other suppliers. We will cover the whole of Brazil, but we focus on where the greatest need of the Brazilian people is,” says Gaunzser.

ViaSat-3 will expand the company’s offering in Brazil, where it has an agreement to use a portion of the strategic communications and geostationary defense satellite (SGDC-1) capability, from Telebras.

The new satellite will allow communication with up to 100 megabits per second (Mbps) download speed.. In Brazil, 23% of households have 51 Mbps internet, according to 2021 data from the Regional Center for Studies on the Development of the Information Society (Cetic.br).

What is the advantage of using three satellites?

The three new satellites will act as a constellation when in space. This won’t make any difference for those who will be using fixed broadband, but there are cases where this connection comes in handy.

This is the case for the aviation sector, where airlines will be able to rely on a single service to offer internet to their passengers during flights from one continent to another, without the need for major moments of interruption.
