The agreement brings together Swedish space services provider SSC Space, Japanese ground station platform developer Infostellar and advanced manufacturing company Seiren to support the operation of the FUSION-1 satellite using a new generation of globally distributed ground station networks.
Under the contract, SSC Space will provide communications services through its recently launched SSC Space Go platform, while Infostellar’s cloud-based StellarStation platform will integrate access to international ground station networks, enabling more frequent communications opportunities and greater operational flexibility for the satellite.
The collaboration reflects a broader shift within the commercial space sector as satellite operators increasingly seek seamless access to geographically dispersed ground stations capable of supporting rapidly growing constellations of small satellites.
As the number of small satellites entering orbit continues to accelerate, operators are placing greater emphasis on accessing international ground station networks that can maximise contact opportunities and improve mission responsiveness.
Rather than relying solely on domestic infrastructure, satellite operators are increasingly turning to virtualised ground station networks that allow communications services to be delivered through a single cloud-based platform, regardless of where individual ground stations are located.
The FUSION-1 mission represents one of the first examples of a Japanese-operated satellite leveraging this emerging international operating model, providing satellite operators with greater flexibility while reducing the complexity traditionally associated with managing multiple communications providers.
The project also demonstrates the increasing maturity of Japan’s commercial space sector as companies expand beyond satellite manufacturing into full-scale satellite operations and downstream data services.
Seiren, which has already established large-scale manufacturing capability for small satellites, views the FUSION-1 mission as an important step in expanding its presence across the broader space value chain.
Company president Hideyuki Yamada said the partnership with SSC Space and Infostellar would significantly enhance the company’s operational capabilities by providing access to international ground station infrastructure and increasing opportunities for satellite communications and data collection.
He said the collaboration would help strengthen Japan’s growing satellite constellation industry while contributing to the long-term development of the country’s commercial space ecosystem.
The agreement also provides Japanese satellite operators with an additional option for accessing global communications infrastructure as demand for Earth observation, communications and space-based data services continues to increase.
For Infostellar, the agreement further expands the capabilities available through its StellarStation platform by integrating one of the world’s largest commercial ground station networks.
Chief executive officer Naomi Kurahara said combining SSC Space Go with StellarStation would provide satellite operators with a broader range of communications services while simplifying access to highly reliable ground station infrastructure through a single cloud-based interface.
The partnership reflects an industry-wide move towards software-defined satellite operations, where operators can dynamically allocate communications resources based on mission requirements rather than fixed infrastructure arrangements.
The contract also represents an important milestone for SSC Space Go, the company’s new ground station service developed specifically to support small satellite missions and commercial constellations.
SSC Space Japan country manager Mac Kanazawa said the agreement demonstrated the company’s commitment to supporting Japan’s rapidly evolving space industry while strengthening relationships across the country’s commercial space ecosystem.
He said the FUSION-1 mission highlighted the value of globally connected ground station services in enabling more efficient satellite operations and supporting the continued growth of innovative space businesses.
As commercial satellite constellations become increasingly central to communications, Earth observation, defence and scientific research, demand for flexible, internationally connected ground station networks are expected to grow rapidly.
For companies such as SSC Space and Infostellar, the FUSION-1 mission represents more than a single satellite contract. It signals the emergence of a new operating model for the global space industry, one where cloud-based platforms and globally distributed infrastructure enable satellite operators to communicate with spacecraft more efficiently, access data more quickly and scale future constellations without the limitations of traditional ground station networks.
