SES and Elveo Mobile plan to establish European manufacturing capability and supply chains for low-Earth-orbit satellites designed to connect directly with ordinary mobile devices, expanding an existing technology and investment partnership into physical spacecraft production.
The companies announced the manufacturing initiative on 15 September as part of a broader collaboration to accelerate direct-to-device services in Europe. The planned satellites will use Elveo’s spacecraft bus, communications payload and software technology and operate as the LEO element of a wider SES multi-orbit network.
No manufacturing location, production rate or factory investment figure has yet been disclosed. The agreement is therefore an industrial commitment rather than a completed capacity expansion, with the detailed production footprint still to be defined.
The underlying communications model is more concrete. Direct-to-device systems are intended to connect standard smartphones, IoT equipment and machines beyond terrestrial cellular coverage without requiring the conventional dedicated terminals associated with satellite communications.
That places different engineering demands on the spacecraft. A satellite has to close a useful communications link with comparatively small, low-power devices on the ground, making antenna performance, radio-frequency design, spectrum access, onboard power and constellation geometry central to system performance.
Elveo brings technology developed through the combination of Lynk and Omnispace, whose merger was completed earlier this year. SES expanded its strategic investment in the combined company in August and agreed to support engineering, operations, market access and regulatory work around the direct-to-device network.
The September announcement introduces the European manufacturing dimension. SES and Elveo say they will work together to establish both production capability and a robust regional supply chain for the LEO spacecraft needed to support European services.
That distinction is important because a low-Earth-orbit constellation is fundamentally a repeat-manufacturing programme. Unlike traditional communications programmes built around a small number of very large satellites, LEO networks depend on producing multiple common spacecraft and replenishing them as the constellation develops.
Repeat production changes the economics and engineering of satellite manufacture. Standardised structures, electronics, software loading, payload integration and environmental testing become more important, while suppliers need enough visibility over expected volumes to invest in tooling and production processes rather than treating each spacecraft as a largely bespoke project.
European production would create opportunities across avionics, RF electronics, antennas, power systems, structures, thermal management, software integration and test. The actual value retained in Europe will depend on how much of Elveo’s existing supply chain is relocated or duplicated and how extensively regional suppliers are incorporated into the final spacecraft.
Supply-chain origin also matters to government customers. SES says the service is intended for commercial users alongside European governments, institutions and defence organisations, including NATO. Those buyers place greater emphasis on the security, resilience and provenance of critical communications infrastructure than a conventional consumer broadband customer.
Manufacturing satellites in Europe does not automatically make every component European. Spacecraft electronics rely on global semiconductor and specialist-component markets, and some technologies may continue to be sourced internationally. It does, however, give the partners greater regional control over assembly, integration, testing and selected critical subsystems.
The LEO network will operate alongside SES’s geostationary and medium-Earth-orbit fleets. Each orbital regime offers different characteristics: LEO provides lower latency and closer geometry to small mobile terminals, while GEO and MEO systems provide other combinations of coverage, capacity and resilience.
SES is positioning the combination as a multi-orbit architecture rather than three isolated satellite services. Traffic can potentially be managed across different layers according to customer, geography and network availability, creating greater resilience when terrestrial infrastructure is unavailable or one orbital system cannot provide the required link.
Elveo also brings 2GHz S-band spectrum rights and what the companies describe as a global market-access footprint covering more than one billion people. Spectrum is a significant part of the industrial proposition because manufacturing satellites without the regulatory rights required to operate them would create capacity with no straightforward route to market.
The system is intended to work with mobile network operators rather than simply bypass them. Direct-to-device services can extend terrestrial coverage into remote regions and provide resilience during network disruption while allowing customers to retain existing mobile devices and service relationships.
That makes time to manufacture important. Several satellite operators are pursuing direct-to-device markets, and service availability will depend on how rapidly operators can place enough spacecraft in orbit to provide credible coverage.
SES and Elveo have not yet stated how many satellites the European production system will need to build or when the first locally manufactured spacecraft will leave the line. Those numbers will determine whether the commitment develops into a major aerospace manufacturing programme or a smaller integration capability.
The industrial direction is nevertheless explicit. The partners are not proposing to serve the European market solely from an external spacecraft supply chain. They intend to establish regional manufacturing around a communications service that SES sees becoming part of its wider GEO, MEO and LEO infrastructure.
The next useful announcements will therefore be physical rather than strategic: factory location, production capacity, supplier selection and spacecraft deployment schedule. Those milestones will put scale behind a commitment that currently establishes the production model without yet defining the size of the European industrial footprint.
