What OHB Hellas does
OHB Hellas is a Greek space systems engineering subsidiary of OHB SE (Europe's third-largest space system integrator), founded in 2018 and operating across three Greek sites (Athens, Patras, Heraklion) with approximately 20 employees. The company specializes in Orbital High-Performance Computing (OHPC), onboard AI/ML for space, advanced manufacturing, and satellite mission engineering services, with a primary G2G and B2B focus on European Space Agency (ESA) and European Defence Fund missions as a subcontractor within the OHB Group consortium.
The company's core products center on ABAX, an Orbital HPC subsystem integrating space-qualified hardware with proprietary firmware virtualization and multi-accelerator support (GPUs, FPGAs, TPUs, NPUs including Google Edge TPU, Xilinx Kria, and BrainChip Akida); GIASAAS, a Satellite-as-a-Service platform providing Kubernetes-based ML inference on space-representative hardware; VULCAN, an ML verification and validation framework for mission-critical systems; and specialized AI applications including fire detection and cloud segmentation built on U-NetV2 architectures for multispectral Sentinel-2 data. The company also delivers traditional space engineering services: requirements engineering, software V&V, documentation management, mission analysis, and mechanical engineering, all ECSS-compliant, supporting flagship ESA missions PLATO and LISA.
Revenue is generated primarily through project-based professional services contracts with ESA prime missions (PLATO, LISA, ODIN'S EYE, ROLIAC) and ESA/EU funded R&D projects (BOLERO, LEO-DIVE, InSPoC-3, NEURO-RESPOND, ARCHIMETIS). The customer base is concentrated in government space agencies and the OHB Group; emerging product revenue from ABAX and GIASAAS is in development. Pricing is contract-based and not publicly disclosed. The company is positioning itself as a center of excellence for orbital HPC and AI/ML in Greece through a five-year partnership with FORTH and quantum technology initiatives.

OHB Hellas competitors and assessment
Company assessmentDirect peers
- KP Labs: Polish space AI company specializing in onboard machine learning and synthetic data generation for Earth observation. Direct collaborator with OHB Hellas in ESA's BOLERO project — both companies compete and partner in the European onboard AI niche.
- Ubotica Technologies: Irish space AI company focused on edge AI inference for satellite onboard processing, including fire detection and cloud detection. Direct competitor in the same niche of Earth observation AI running on edge accelerators (Google Coral, Myriad).
- SITAEL: Italian smallsat and AI company with proprietary satellite platforms and onboard AI capabilities. Comparable in offering end-to-end small satellite solutions with embedded AI/ML, particularly for Earth observation and IoT.
Emerging players
- HE Space Operations: European space engineering services company providing specialist contractors to ESA and European primes. Comparable in offering space systems engineering talent and documentation/V&V services, but operates as a staffing/services firm rather than a product company.
- Leaf Space: European emerging player providing ground segment-as-a-service for satellite operators. Indirectly comparable in the Satellite-as-a-Service vision OHB Hellas pursues with GIASAAS, though focused on ground communications rather than orbital AI.
Broad incumbents
- GMV: Large Spanish space systems integrator with broad portfolio in satellite navigation, ground systems, and space AI. Overlaps with OHB Hellas in ESA mission engineering services, space systems integration, and onboard software V&V, but at vastly greater scale across all of Europe.
- Telespazio: Italy-headquartered large space services company (Leonardo/Thales joint venture) covering mission operations, ground systems, and satellite services. Overlaps with OHB Hellas in ground segment software (e.g., E2E CMMS) and ESA mission support but at enterprise scale.
- Beyond Gravity (formerly RUAG Space): Swiss space hardware supplier providing satellite structures, payload electronics, and avionics. Direct adjacency to OHB Hellas's spacecraft avionics and flight computer focus, but operates as a tier-1 supplier with broader product portfolio.
- Kongsberg Defence & Aerospace (Space): Norwegian defense and space company with satellite subsystems and onboard electronics for ESA missions. Provides comparable space electronics and embedded computing capabilities, though as part of a much larger defense portfolio.
- SENER Aeroespacial: Spanish space engineering firm providing mechanisms, onboard electronics, and systems for ESA missions. Comparable in providing ESA-grade mechanical engineering and onboard systems, with similar positioning as a mid-sized European space specialist.
