KA-SAT Satellite Provides Global Broadband Internet Coverage

The KA-SAT satellite is a game-changer for global broadband internet coverage. It offers seamless connectivity to rural and remote areas, where traditional internet infrastructure is scarce.

KA-SAT has a high-throughput Ka-band satellite that provides fast and reliable internet speeds. With a capacity of 70 Gbps, it can serve a large number of users simultaneously.

The satellite's beam can reach even the most remote areas, providing internet access to people who previously had no connection. This is especially valuable for communities that rely on internet access for education, healthcare, and economic opportunities.

The KA-SAT system can achieve a total capacity of more than 90 Gbit/s thanks to its high level of frequency reuse.

This is made possible by the satellite operating in conjunction with ten terrestrial teleports, two of which serve as a backup, providing Internet gateway services.

The KA-SAT ring, a terrestrial telecommunication high-speed network, links all the teleports together, enabling efficient data transfer.

These teleports also provide parts of the Eutelsat's Tooway service, which is a key component of KA-SAT's offerings.

The KA-SAT spacecraft is equipped with four multi-feed deployable antennas, providing enhanced pointing accuracy and high-efficiency repeaters.

Each spotbeam is associated with a 237 MHz wide transponder, allowing a data bit rate throughput of 475 Mbit/s per spot. This means that the spacecraft can handle a significant amount of data transmission.

The spacecraft power is about 14 kW, with the payload DC power being 11 kW. This is provided by the solar array, which can deliver up to 16 kW of power.

The payload mass is approximately 1000 kg, while the dry mass is around 3170 kg. This highlights the complexity and size of the spacecraft.

The launch mass was 6100 kg, indicating the significant resources required to get the spacecraft into orbit.

KA-SAT's broadband internet service is a high-capacity system that can achieve a total capacity of more than 90 Gbit/s due to its advanced frequency reuse technology.

The service is operated in conjunction with ten terrestrial teleports, two of which serve as a backup, providing internet gateway services and parts of the Eutelsat's Tooway service.

These teleports are all linked by the "KA-SAT ring", a high-speed terrestrial telecommunication network that enables seamless connectivity.

The service is centrally operated from Skylogic's NOC in Torino, Italy, which is a subsidiary of Eutelsat.

KA-SAT offers satellite television services, which can be accessed using a KA-Band feedhorn LNBF.

The Irish Saorsat TV service is one of the services carried by KA-SAT, providing TV access to areas in Ireland where Saorview is not available.

Ka-band technology offers a cost-effective solution with higher quality, better performance, and higher speed services.

By using Ka-band, you can achieve much higher throughput using the same amount of bandwidth, driving down the cost of the spectrum and the cost per bit.

Ka-band spot beams often have 10 times more capacity than traditional Ku-band satellites.

Avanti HTS systems employ spot beam architectures that support large-scale frequency reuse to deliver more capacity and higher data rates.

The gain of a dish antenna is proportional to the frequency being used, allowing you to use a smaller dish to get an equivalent power output up to the satellite.

This means that RF amplifier requirements are reduced.

Viasat and Eutelsat established a joint venture in 2016, which owned 51% and 49% of Euro Broadband Infrastructure (EBI) respectively.

The joint venture operated KA-SAT and a wholesale broadband distribution business.

Eutelsat opted to build its own Konnect Very High Throughput Satellite in 2018, causing the companies' strategies to no longer align.

Viasat and Eutelsat are winding down their joint venture in a thoughtful way.

The purchase price for EBI's assets is 140 million euros, which may be adjusted up or down by up to 20 million euros depending on certain EBI revenues achieved.

Eutelsat owned 51% of EBI, while Viasat owned 49%.

Viasat plans to purchase the remaining assets of the joint venture from Eutelsat.

The deal ends the joint venture between Viasat and Eutelsat, which was established to support Viasat 3 satellite coverage of Europe, the Middle East, and Africa.
