en.Wedoany.com Reported - On July 7, 2026, Japanese small satellite manufacturer Seiren Co., Ltd. finalized a tripartite satellite communications contract with global space service provider SSC Space and cloud-based ground station operator Infostellar.
Under the agreement, the three parties will build an international automated "Ground Segment as a Service" (GSaaS) channel to support telemetry, tracking, and command (TT&C) operations for Seiren's upcoming FUSION-1 technology demonstration mission.
This commercial collaboration marks a structural maturation of Japan's commercial space ecosystem. Through the agreement, large industrial manufacturing groups can move away from sole reliance on traditional state-owned ground tracking infrastructure toward flexible, software-defined global antenna networks.
For telemetry and payload tracking of the FUSION-1 mission, the matrix integrates SSC Space's hardware assets with Infostellar's managed cloud virtualization software engine. Specifically, Infostellar's proprietary cloud virtualization platform, StellarStation, serves as the mission's core software interface, responsible for receiving orbital overpass profiles, dynamically matching FUSION-1's tracking windows with geographically optimal ground antennas, and handling radio frequency (RF) licensing acquisition and regulatory frequency coordination on a unified console. The automated scheduling loop directly maps to the SSC Space Go network—a specialized small satellite ground network layer recently deployed by SSC Space (formerly Swedish Space Corporation). The FUSION-1 mission will have priority access to this network's globally distributed compact 4-meter-class antenna rings, capable of operating in S, X, and Ka-band frequencies. The architecture also supports dual-polarization payload downlinks, routed through highly secure, multi-tenant ground facilities located at the Esrange Space Center in northern Sweden, Inuvik in northern Canada, and Punta Arenas in southern Chile.
The FUSION-1 mission marks a significant business expansion for Seiren Co., Ltd. Founded in 1889 as a traditional integrated textile and industrial materials manufacturer, Seiren has leveraged its core competencies in precision weaving, automated assembly, and high-durability polymer technology over the past decade to gradually expand into aerospace hardware. The company initially validated its satellite manufacturing capabilities by leading the structural development of the Fukui Prefecture Civil Satellite Project, which successfully launched the RWASAT-1 CubeSat in 2021. Supported by strategic subsidies from Fukui Prefecture, Seiren collaborated with radar imaging specialist Synspective to establish an active small satellite platform and synthetic aperture radar (SAR) antenna array production line. The FUSION-1 mission will serve as a pathfinder for the company's end-to-end mission control operations, laying the foundation for exporting Japanese-made commercial satellite constellations to international operators.
The integration of Seiren's hardware with international ground networks aligns with the broader trend of ground segment cloudification in the Asia-Pacific space market. As Japan's demand for continuous Earth observation data and low-latency Internet of Things (IoT) applications grows, satellite operators relying solely on local fixed antenna arrays constrained by terrain obstructions and weather interference will face bottlenecks. By leveraging virtualized ground architectures, Japanese space companies can bypass the high capital expenditure of building dedicated ground terminal infrastructure, thereby reducing operational overhead, ensuring high link availability through automated global path diversity, and accelerating time-to-market for commercial constellations with multi-satellite configurations across different orbital planes.
