Spacebus Neo: the ideal platform for very high throughput telecom satellites!
Today we want to be connected anywhere and anytime; we want to have access to more and more content at any given moment; we want to eliminate all shadow zones and bridge the digital divide to ensure connectivity anywhere in the world. Satellite telecommunications systems, especially the digital variety, are undoubtedly the best solution to meet the requirements of a fast changing and fiercely competitive market.
VHTS for all!
In April 2018, Eutelsat Communications (Euronext Paris: ETL) chose Thales Alenia Space to build a next-generation very high throughput satellite system (VHTS), dubbed KONNECT VHTS. Featuring high power and capacity (about 500 Gbps in instantaneous data rate), coupled with flexibility and versatility, this VHTS system will adapt to changing demand in Europe for fixed and mobile, government and commercial connectivity. The KONNECT VHTS satellite will weigh over 6,000 kg at launch. It will be built on an all-electric Spacebus Neo platform, compatible in particular with the upcoming Ariane 6 launch vehicle. Working in conjunction with land networks, this satellite and its very powerful digital processor will support the deployment of high-speed Internet access in sparsely populated and isolated regions – providing a universal solution to bridge the digital divide for everybody. This contract confirms the leadership of Thales Alenia Space in terms of connectivity via satellite.
Fast like a cheetah: VHTS solutions support the development of High-speed Internet
Thales Alenia Space spearheads the VHTS trend, which is based on digital technology to offer tremendous operational agility. This type of solution first appeared in military telecommunications, and more recently made its entry in the commercial market. Today, operators want more, for good reason. VHTS systems combine high capacity, digital agility and competitiveness. Highly flexible, they are capable of adjusting throughput to match the requirements of the coverage zone at any given moment. In other words, these high-tech payloads meet the evolving needs of operators throughout a telecom mission.
Flexible like a chameleon: new digital payloads are both agile & flexible
At the recent Toulouse Space Show, Jean-Loïc Galle, President and Chief Executive Officer of Thales Alenia Space, said: “We won the VHTS contract for the most powerful satellite in the world and also the most competitive, in terms of cost per megabyte, thanks to R&D work on VHTS payloads by ESA and CNES.

However, to house this type of high-capacity payload, you also need a state-of-the-art platform – and that is the case with the Spacebus Neo from Thales Alenia Space.
The dynamic duo: VHTS digital payload + Spacebus Neo platform
Smart like a dolphin: A VHTS digital payload associated to an electrical Spacebus Neo platform is the perfect match
Spacebus Neo is the new family of platforms from Thales Alenia Space for geostationary telecommunications satellites. All Spacebus Neo platforms now feature all-electric propulsion, and combine higher performance, greater robustness, modular design and higher power. Electric propulsion means a drastic reduction in satellite launch weight. And of course, the lower the weight of the platform, the bigger the payload it can carry. The VHTS payload matched to the all-electric Spacebus Neo platform makes for a very dynamic duo.
Spacebus Neo: latest news
Four Spacebus Neo-based satellites have already been ordered by commercial and government customers1, with a first launch planned for 2019.
The Spacebus Neo program recently passed a key milestone, the Critical Design Review.
These platforms include a number of innovations, not only all-electric propulsion, but also:
• Highly innovative thermal control and a high-performance power subsystem, enabling an effective 3D organization of the powerful payload.
• Flexible and modular design, in order to both reduce manufacturing cycles and also enhance the satellite’s capability for its telecom mission.
• Payloads tailored to each customer’s requirements, including flexible digital solutions and very high data throughput.
Production and qualification of the Spacebus Neo product line is continuing apace at Thales Alenia Space. A large European consortium2 is also contributing to this product.
The electric propulsion module (XPS) is assembled under the responsibility of Thales Alenia Space in the UK, while the avionics module is integrated by Thales Alenia Space in its Cannes plant. Structural parts of the payload module are delivered to Thales Alenia Space in Toulouse to be integrated with the payloads.
