Eutelsat Quantum - a new generation communication satellite
The Eutelsat Quantum satellite of Paris-based Eutelsat Communications marks a revolutionary step forward for commercial satellites, offering unprecedented customization and flexibility. 1)
1) A pioneer in the field of commercial satellites
The Eutelsat Quantum satellite is a world first, marking the start of a new era of commercial satellites. Putting agility and flexibility in the hands of our customers, the satellite paves the way for dynamic resource management to meet changing demands in realtime.
Traditionally, commercial satellites are designed for a fifteen year lifetime. However, with a three-year procurement and building phase, their design must take into account the needs to be addressed over a cycle of eighteen years, despite evolving markets and commercial environments.
Eutelsat Quantum's revolutionary approach can be summed up in one word: flexibility. Flexibility in coverage, power, frequency and bandwidth. Each of these features can be reconfigured in-orbit throughout the satellite's lifetime, to efficiently serve applications and ensure optimal use of resources at all times. Customers will no longer have to predict market requirements or anticipate changes in the future: with this new way of managing day-to-day operations they will be able to tailor coverages to their immediate needs.
2) A software-driven satellite
Eutelsat Quantum represents the culmination of many years of research and evaluation driven by Eutelsat, and supported by major partners such as the ESA, the UK Space Agency, and Airbus.
Powerful operational software ensures that the payload resources are used as efficiently as possible, to predict, operate and manage the on-board configuration and reconfiguration of the satellite. This level of flexibility requires the ability to accurately simulate, optimize and control the satellite once it is in orbit.
Our customers will have their own software to implement the on-board configuration they require, while operators manage and operate the satellite in its optimal configuration without interference within the satellite or with other nearby satellites.
3) A new standard of customization
The satellite's flexible behavior enables it to adapt to its environment, giving customers in the government, mobility and data markets the ability to vary coverages based on their immediate needs and allocate resources between beams and regions, optimizing their capacity use. The majority of Eutelsat Quantum's capacity has already been reserved, notably by American operator, Peraton, demonstrating the commercial interest in the satellite.
While Eutelsat Quantum's flexibility in terms of coverage, power and spectrum reconfiguration is significant, its beam tracking and hopping capabilities extend its boundaries even further. Beam reconfiguration enables Eutelsat Quantum to track mobile terminals. For example, in the marine industry, a beam can now be reconfigured to seamlessly track the progress of a terminal across an ocean, without having to lease multiple beams to cover the relevant regions.
4) A forerunner in tomorrow's space industry
Eutelsat Quantum is leading the way for a paradigm shift in building telecommunications satellites.
Taking inspiration from Eutelsat Quantum, satellites built according to a standard specification and configured in orbit could be mass produced, unlike the custom-made production of traditional satellites, which are configured during construction. Eutelsat Quantum could be the first step in a "quantum leap" forward for the satellite communications industry, while at the same time meeting the evolving needs of our customers.

Eutelsat Quantum will be the first generation of universal satellites able to serve any region of the world and adjust to new business without the user needing to procure and launch an entirely new satellite. Featuring phased array antennas and flexible connectivity, which is fully reconfigurable in orbit, Quantum will be able to adjust its coverage and capacity to suit customers' needs as and when they change.
Airbus used its Portsmouth facility to develop the adaptable telecoms payload, and its subsidiary SSTL (Surrey Satellite Technology Ltd) in Guildford to make the spacecraft bus, or chassis.
The first Quantum satellite will have a launch mass of 3,500 kg and an all Ku-band communications payload mass of 450 kg. It will be launched using conventional thruster propulsion and will have a designed lifespan of more than15 years.

- The assembly of Eutelsat Quantum took place in the Airbus facility in Toulouse, France, on 10 May.
- The satellite has been developed as an ESA Partnership Project with satellite operator Eutelsat and satellite manufacturer Airbus, under ESA's program of ARTES (Advanced Research in Telecommunications System), leveraging on SSTL (Surrey Satellite Technology Ltd), which provided the satellite's innovative platform.
- Eutelsat Quantum will allow its users to actively define and shape the performance and reach they need from the satellite.
- Because Eutelsat Quantum takes a software-driven approach, changes can be made while it is in orbit, such as adjusting the satellite's coverage, frequency and power, which enables it to operate from any orbital position.

- The successful mating of the payload and platform demonstrates the excellent capabilities of Airbus, Surrey Satellite Technology Ltd and their suppliers, both in the conception and the realization of the new technologies deployed in this innovative satellite.
- ARTES Partnerships Projects help European and Canadian space industries to develop new products and services, supporting the introduction of novel technologies and solutions that might not otherwise reach the market.
- The Quantum partnership has the strong backing of the UK Space Agency and includes Airbus UK as prime contractor and payload provider. With Surrey Satellite Technology Ltd, Airbus UK manufactured and integrated most of the satellite's cutting-edge equipment.
- The completed satellite will now be tested under the harsh conditions needed to simulate both launch and the space environment in which it will orbit the Earth.
• January 9, 2019: SSTL (Surrey Satellite Technology Ltd.) has completed the build of the platform for Eutelsat Quantum, the world's first geostationary telecommunications satellite that will be fully reconfigurable in orbit. Today, the SSTL satellite platform was handed over to Airbus who will complete the satellite assembly and testing in Toulouse. 4) 5)
- The Eutelsat Quantum platform consists of a precision-engineered composite central thrust tube standing at 2.5 m tall which houses a bipropellant chemical propulsion system that will enable the satellite to stay on station throughout its 15 year lifetime, and SSTL's newly developed GEO momentum wheels and gyro which will maintain the satellite in a stable attitude and enable adjustments in the satellite's orbital position.
- Sarah Parker, Managing Director of SSTL said "The completion of our work on the Eutelsat Quantum satellite platform is an important milestone for SSTL as it represents our first venture into the global commercial telecoms satellite market. The design and assembly of this innovative spacecraft has enabled us to advance the knowledge and skills required to develop highly capable satellite products for the evolving telecoms market, where we are actively engaged in seeking new opportunities."
- Quantum has emerged from a project initiated in 2014 and originally codenamed "AnySAT".
