Ground segment (gs) r&d collaboration with korea & france for eutelsat quantum-class satellite

Eutelsat is developing a new innovative quantum-class satellite that utilizes beam hopping technology, in order to deliver a much more flexible and cost efficient & effective satellite services in orbit by developing the critical ground segment in cooperation with asat/etri in korea

To ensure competitiveness satellite communications must continue to evolve. In general, the expensive in-orbit satellite resources are not fully utilised in the market. By developing "Beam Hopping" satellite communication system, the overall system ensures that the optimum payload resources are used at all times, over an increased coverage region, improving efficiency that ultimately lead to reduced cost. Eutelsat is developing a new innovative Quantum-Class satellite introducing among others, the Beam Hopping technology, in order to deliver a much more flexible and cost efficient effective satellite services in orbit. As described in the paper “Eutelsat QUANTUM-class satellite: beam hopping” , the principle of the Quantum beam hopping, is that a single beam is redirected to different areas synchronously with the contents to be delivered. In such a way, remote terminals spread over a very large area can share in time the same capacity with neither loss of performances nor waste of satellite resources. The counterpart of this technique is that it involves a high level of complexity for the synchronization of the ground segment with the space craft, in particular the advanced beam forming networks (BFNs) enabling the antennas to redirect instantaneously and seamlessly the beam to different geographical areas. The Eutelsat Quantum Class of satellite is an industry game changer. It is capable of flexibility and in-orbit reconfiguration in terms of coverage, power and spectrum. One such functionality is the ability to beam and coverage hop. Beam hopping is a fast reconfiguration of the beam over a path or separate distinct locations. Since Eutelsat Quantum is capable of providing a variety of beam shapes, this hopping sequence can consist of beams that match the traffic demand. Each beam within the sequence can be reconfigured in orbit, not just to adjust the footprint but also the dwell time of each hop. With such ability, Eutelsat Quantum is able to more efficiently match the traffic demands over a large region, each served by a more optimised beam size and shape. Such flexibility makes it applicable to a variety of applications. In this project, the consortium aims to develop and test the Quantum satellite ground segment (Hub + User terminals) as follows; (1) Enhance the efficiency of Satellite bandwidth and constitute the environment of satellite communication more friendly to the consumers, who so far were afraid to go forward due to the expensive operation cost of satellite bandwidth. More consumers can be generated by the more cost-effective bandwidth via Quantum technology. More market can be created by this new & efficient technology, including those applications so far withheld. (2) Ground Equipment for Hub & Terminal need to be developed, to support the beam hopping technology of Quantum satellite. (3) Field test of Hub & terminal including modem under the simulated Quantum satellite environment (4) The final product should be stabilized and reduced to smaller size for the commercialization
