Surrey Satellite Technology Ltd (SSTL) has completed the build of the platform for Eutelsat Quantum, the world’s first geostationary telecommunications satellite that will be fully reconfigurable in orbit.
The Eutelsat Quantum satellite is being built under a public–private partnership between the European Space Agency (ESA) and satellite operator Eutelsat with Airbus as the prime contractor. Today the satellite platform, which has been designed and manufactured by SSTL in Guildford, was on view to invited guests at a special event to mark the handover to Airbus who will complete the satellite assembly and testing in Toulouse.
The Eutelsat Quantum platform consists of a precision-engineered composite central thrust tube standing at 2.5 metres tall; it houses a bi-propellant 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.
Speaking about the project, 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 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.”
Colin Paynter, Managing Director, Airbus Defence and Space UK, added: “Combining the payload expertise from Airbus in Portsmouth, and SSTL’s new geostationary platform provides a very sophisticated package for Eutelsat. The satellite is a world first, fully reprogrammable in orbit, and we’re looking forward to seeing it fly.”
The Eutelsat Quantum satellite will be able to adapt to new demands in coverage, bandwidth, power and frequency, enabling it to operate effectively from any orbital slot. 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, Eutelsat Quantum will be able to adjust its coverage and capacity to suit customers’ needs as and when they change.
Yohann Leroy, Deputy CEO and CTO at Eutelsat, commented: “Eutelsat Quantum is a world first and the culmination of many years of research by Eutelsat. Its premium capacity will enable us to offer game-changing optionality and flexibility to our customers in the government, mobility and data markets, who will be able to operate and optimize capacity to adjust coverages in real time, and to do so autonomously. We are delighted to co-operate with our long-standing partners, the ESA, the UK Space Agency and Airbus, and to be able to rely on the world-leading expertise within the UK space industry.”
Eutelsat Quantum uses technology developed by Airbus and SSTL in the UK under the ESA Advanced Research in Telecommunications Systems programme (ARTES) and supported by the UK Space Agency.
