Space-SI

What Space-SI does

Space-SI (legal name Center odličnosti Vesolje-SI) is a Slovenian Centre of Excellence for space sciences and technologies headquartered in Ljubljana with engineering facilities including an ISO class 8 clean room and two ground stations (Axyom near Pomjan and the transportable STREAM in Ljubljana). The organization designs and operates micro- and nanosatellite platforms — most notably the NEMO-HD Earth observation microsatellite launched on September 3, 2020 aboard a Vega rocket — and runs its own mission operations and data downlink through its ground station network. Its proprietary STORM processing chain provides fully automatic optical satellite data processing (orthorectification, atmospheric correction, change detection, NDVI) across eight-plus sensor types including NEMO-HD, Landsat, WorldView, RapidEye, Pleiades, SPOT 6, THEOS and PROBA-V, and it has developed image-based satellite attitude control technology that reuses the Earth-observation sensor for guidance and formation flying.

The entity serves three principal customer groups: Slovenian and EU public-sector buyers (Republic of Slovenia via CMSR, Administration for Civil Protection and Disaster Relief) for environmental and disaster-monitoring data; international scientific missions (RAVE, Gaia, Kepler, Planck, Swift, Fermi, INTEGRAL, PRISMA) where it contributes scientific expertise, telemetry and data analysis; and bilateral development partners (e.g., JKUAT in Kenya, C3M) for applied Earth observation in water and climate projects. Revenue is generated through government contracts and grants, monetized satellite data products, and technology development/professional services, with pricing not publicly disclosed and engagement conducted via project-based agreements rather than standard product pricing.

It runs two ground stations (Axyom and STREAM), an ISO class 8 clean room for satellite integration, and the proprietary STORM automatic satellite data processing chain that turns raw optical imagery into map-ready products for disaster response, environmental monitoring, agriculture, and urban planning use cases.

Product overview

Space-SI (Center of Excellence Vesolje-SI) is a Slovenian space research organization operating a comprehensive Earth observation system built around the NEMO-HD microsatellite as its core product. The organization combines satellite operations (NEMO-HD Mission Operations) with ground infrastructure (two ground stations: Axyom and STREAM) and advanced data processing capabilities through the STORM Processing Chain for fully automatic satellite data processing. Space-SI provides Remote Sensing Services for various applications and conducts Space Exploration Research including astrophysics and participation in international space missions. Additional capabilities include a Clean Room Laboratory for satellite integration and Micro and Nanosatellite Technologies R&D for next-generation satellite platforms.

Broad incumbents

• OHB System AG: OHB is a European space prime contractor building satellites, spacecraft, and space systems for institutional customers including ESA and national space agencies. It represents the larger institutional incumbent Space-SI competes against for EU program funding and partnership roles on flagship missions.
• Spire Global: Spire operates a nanosatellite constellation delivering weather, maritime, and aviation data products. Its model of monetizing space-derived data through subscription analytics — rather than imagery sales — is a structural alternative to Space-SI's STORM-based EO processing pipeline.
• Satellogic: Satellogic operates a commercial sub-meter Earth observation constellation and sells imagery and analytics to government and commercial customers. As a vertically integrated EO data provider, it represents the scale of competitor Space-SI would face if it commercialized NEMO-HD data more broadly.
• German Aerospace Center (DLR): DLR is a national research center conducting space research, satellite development, and Earth observation in Germany. As a peer national space research institution with similar mandate (government-funded space R&D, mission participation, EO applications), DLR is a direct analogue for Space-SI's Centre of Excellence model at larger scale.
• Planet Labs: Planet Labs operates the world's largest commercial Earth observation satellite constellation (200+ Dove satellites) and provides daily global imagery — competing head-to-head with Space-SI's NEMO-HD-derived data products for government and commercial customers in agriculture, disaster response, and environmental monitoring.

Direct peers

• Open Cosmos: Open Cosmos designs, manufactures, and operates small satellites for commercial and government customers with an end-to-end mission service model. As a younger smallsat platform company targeting EO and IoT applications, it competes with Space-SI for institutional and international development contracts.
• GomSpace: GomSpace is a Danish nanosatellite manufacturer and operator offering complete platforms and subsystems for academic, government, and commercial missions. Its business model of providing affordable small-sat platforms for emerging space programs closely parallels Space-SI's role for Slovenia and partner countries.
• Kongsberg NanoAvionics: NanoAvionics is a smallsat bus manufacturer and mission integrator serving commercial constellation operators, research institutions, and government customers. Its combination of bus manufacturing, integration services, and mission operations mirrors Space-SI's full-stack approach with NEMO-HD and its ground stations.
• Surrey Satellite Technology Ltd (SSTL): SSTL is a pioneer in small satellite manufacturing and Earth observation, originating as a university spin-out (University of Surrey). Like Space-SI, SSTL built its reputation on affordable microsatellite platforms and national-capacity space programs, making it a direct analogue for a small-team research center delivering operational satellites.
• AAC Clyde Space: AAC Clyde Space manufactures small satellites and subsystems, and provides mission services for Earth observation and IoT. Like Space-SI, it is a small satellite platform provider serving research institutions, government agencies, and commercial constellation operators with end-to-end mission capabilities.
