OHB Hellas and Parsimoni to Build Secure Sovereign In-Orbit Software Platform
CEO
We are pleased to announce a strategic collaboration with OHB Hellas, the Greek subsidiary of the OHB SE group, to develop a secure, sovereign in-orbit software platform for European space missions.
This project combines OHB Hellas' Versal Orbital HPC hardware -- a high-performance computing solution designed for orbital environments -- with the Parsimoni Satellite App Store, our ESA-supported marketplace that allows satellite operators to deploy, manage, and monetise software applications in orbit.
What We Are Building
The first commercial offering under this collaboration will integrate the Satellite App Store with the Versal Orbital HPC hardware and feature OHB's specialised fire detection and cloud detection applications, demonstrating immediate utility for Earth observation missions.
The platform uses SpaceOS's security-first architecture -- zero trust, post-quantum cryptography, and CCSDS/SDLS compliance -- to provide strong isolation between applications running on shared hardware. This allows satellite operators to repurpose assets mid-mission, shifting from fixed mission profiles to real-time responsive operations.
European Sovereignty
This partnership addresses a growing need for European-controlled space infrastructure. Both the Versal Orbital HPC and SpaceOS are developed in Europe, and the Satellite App Store project has been supported by the European Space Agency (ESA). By combining locally developed hardware and software, the collaboration supports strategic autonomy for European space missions.
Background
OHB has been a validation partner for SpaceOS since 2023, when we first began developing the platform. This collaboration marks the first dedicated joint project, building on several years of technical exchanges and shared ambition to make satellite operations more flexible and secure.
