The need for flexibility Commercial satellites are traditionally designed for a fifteen-year lifetime. With a three-year procurement phase, designs must be viable and marketable for eighteen years. However, markets change, and political and commercial environments evolve. The EUTELSAT QUANTUM satellite offers a revolutionary approach to satellite system design. Enabling a real-time response to changing requirements, satellite resources can be optimized for the best performance at all times. Increased flexibility has often led to increased hardware or more complex and costly systems. The EUTELSAT QUANTUM satellite, however, does not need any additional design for future missions and is orbital slot agnostic. Clients no longer need to predict market requirements, anticipate changes or have multiple leases. With flexible coverage, power and spectrum, the innovative EUTELSAT QUANTUM satellite responds in real-time to evolving requirements, providing an efficient, dynamic response to different types of applications. Clients can tailor coverages to their immediate needs, balance resources between beams and regions, and thereby benefit from a higher fill-rate and improved inventory management. Specifically designed client-side software enables the satellite resources to be planned and managed efficiently, to respond to evolutions in demand, pre-plan, or simply harmonize requirements.

COVERAGE FLEXIBILITY Independent antenna systems provide uplink and downlink footprints which can be individually defined in terms of shape, size and location. Eight beams, four per polarisation, in both uplink and downlink can be reconfigured from small spot beams to widebeam coverages over anywhere on the visible earth. As they are fully independent, the downlink beam can have a completely different coverage from the uplink. They can also be independently optimised so that the smallest beam possible provides the highest gain. Each beam can be split into multiple, simultaneous regions of similar or differing size in a seamless manner. FLEXIBLE POWER ALLOCATION Power allocation can be managed between each beam and channelizer. Coupled with the ability to define coverages to the smallest size necessary for the application, thus maximising antenna gain, power can be efficiently managed and shared between beams and channelizers wherever and whenever required. This is particularly useful when load balancing to match and balance surge requirements between beams. SPECTRUM MANAGEMENT Operating over the FSS bands of 13.0-14.8 GHz in uplink and 10.70-12.75 GHz in downlink, and with variable channel bandwidths between 54 MHz and 250 MHz, the EUTELSAT QUANTUM satellite offers flexible interconnectivity over the full visible earth. This enables an independent orbital solution for all three ITU regions which can be deployed for a variety of applications, optimizing satellite resources at all times. EUTELSAT QUANTUM offers flexible channelization and translation, variable channels in steps of 1 MHz, channel centres in steps of 0.5 MHz, and frequency reuse.

Beam switching The flexible nature of EUTELSAT QUANTUM can be considered for a variety of applications. Combined with the adapted ground technology (gateway and modems) beams can be switched or reconfigured to track mobility applications in slower time, or hopped for rapid and seamless coverage of multiple, spatially diverse regions. Beam hopping is based upon DVB-S2X Annex E and the Super Frame structure. The satellite is capable of supporting eight independent beam hopping networks when using the appropriate ground technology. Each beam can be hopped up to a maximum of 32 times; when applied to the capability of splitting the beam, this vastly extends the simultaneous coverage response.

Beam reconfiguration enables the satellite to track mobile terminals, including aircrafts, maritime vessels, RPAS (Remotely Piloted Aircraft Systems) and other mobile units. For mobility applications, for example, a beam can be reconfigured to seamlessly track the progress of a terminal across an ocean. The system uses a smaller, more optimised coverage of the terminal, resulting in a higher antenna gain. Given the flexibility of the system, each hop can be a variety of shapes and sizes to match the application and demand. Taking the beam reconfiguration a step further, the EUTELSAT QUANTUM satellite can coverage hop in a rapid, seamless manner. Beam hopping is a fast reconfiguration of the beam over a path or set of diverse locations. As the satellite can provide a variety of beam shapes, the hopping sequence can consist of regions that match the traffic demand. Each footprint within the sequence can be reconfigured in orbit to adjust the shape and time of each hop. Traffic demands over a large region are therefore met more efficiently, as each requirement is served by an optimised beam size and shape.

Beam tracking The EUTELSAT QUANTUM satellite can potentially offer up to eight simultaneous, independent, beam-hopping networks when using the appropriate ground technology. These can be applied to mobility applications or to diverse, static locations, with maximum capacity distributed between the beams in a seamless manner.

TRACKING Example of tracking for mobility applications. Reshaped and steered beam activation is scheduled to follow the remote mobile terminals route, optimizing performances.

Mitigating interference In today’s environment a secure and robust system is critical. The EUTELSAT QUANTUM satellite offers dynamic reconfiguration, enabling coverages to be quickly modified to exclude the location of an interfering signal.

In the frequency domain, the spectrum flexibility provides spectral nulling in the event of intentional or unintentional signal interference, whilst the coverage can be reconfigured to apply a null over the interfering region. Either or both solutions can be applied to ensure minimal impact and maintain integrity of service. With geo-location and encryption in both Telecommand and Telemetry, EUTELSAT QUANTUM offers a secure and robust satellite system.

Giving control to the client With the EUTELSAT QUANTUM satellite, clients take direct control of their own resources, essentially becoming a virtual satellite operator. A suite of powerful operational software, called the EUTELSAT QUANTUM Cockpit, puts the client in the driving seat, ensuring that payload resources are used as efficiently as possible and tailored to their needs. The EUTELSAT QUANTUM Cockpit enables clients to predict, operate and manage the on-board mission configuration and reconfiguration. With this remarkable level of flexibility, resource strategies can be accurately simulated or optimised for each mission and the satellite controlled once it is in orbit. Clients can plan and anticipate requirements with their own Cockpit tool, while operators can manage and operate the satellite at its optimum configuration without interference within the satellite or to others in the satellite neighbourhood.

Typical use cases EVOLVING SITUATIONS, E.G. SPECIAL OPS, SNG, GOVERNMENTAL & EMERGENCY RESPONSE The most basic advantage of coverage flexibility is to reconfigure uplink or downlink footprints as markets evolve. A coverage can become larger or smaller, or vary in shape and power as requirements change, and a single beam can evolve in time. For example in scenario A, a 53-54 dBW beam is placed over a specific region.

SCENARIO A

SCENARIO B

As the situation evolves, the beam shape morphs to match the change, as shown in scenarios B and C. Beams can also be split to cover more than one region, as illustrated in scenario D. Even though the satellite provides eight independent beams, it can cover many more regions. Beam splitting does not need to be equal. For example, a small part of the beam can be used to cover a gateway whilst simultaneously covering a larger region elsewhere.

SCENARIO C

SCENARIO D

DAILY, SEASONAL AND LONGER-TERM VARIATIONS Coverage reconfiguration allows beams to be relocated over large portions of the earth. The maritime industry, for example, can have demands over both the Mediterranean and Indian Ocean at different times of the year. Rather than leasing two differing coverages one for each period of the year, a single beam can be reconfigured for these specific times. The reconfiguration can be extended further to cover the transitional period between the two areas from a single beam. This in-orbit reconfiguration can similarly be applied to governmental and emergency situations which require capacity allocation over countries and regions for an indefinite period of time, after which they can be moved elsewhere.

EXAMPLE OF SEASONAL COVERAGE VARIATION In winter, the coverage is over the Caribbean Sea where the fleet operates.

In summer, the coverage is moved over the Mediterranean Sea where the fleet now operates.

Beam and channelizer power and load can also be balanced in response to peak demands within a daily variation. In the third image opposite, two beams cover different parts of the globe, providing peak and low capacity at different times. Power is balanced between the beams resulting in a lower overall capacity requirement.

EXAMPLE OF DAILY VARIATION LOAD BALANCING Scheduled resource allocation. 22

DEFENSE APPLICATIONS With reconfigurable coverage, spectrum, power, geolocation and beam hopping, and a client software tool to manage dynamic requirements, the EUTELSAT QUANTUM satellite readily adapts to defense needs. Operations can be harmonised and coordinated, with an optimised response at all times. RPAS for instance, can be served via shaped beams over flight paths before moving into a theatre of operation served by a more static beam, which itself can be reconfigured once the situation is resolved. With encryption in both Telecommand (NSA approved) and the payload Telemetry (AES), the EUTELSAT QUANTUM satellite offers a secure and robust satellite system. For government and defense satellite communications, the ability to be a Virtual Satellite Operator, with the definition and command of requirements in isolation, ensures secure, autonomous control. In addition, cross-industry collaboration enables the EUTELSAT QUANTUM payload to meet the U.S. government’s stringent Information Assurance (IA) and Cybersecurity requirements.
