OHB Hellas and Parsimoni announce joint project to develop a secure, sovereign, in-orbit software platform to accelerate value creation in orbit

OHB Hellas and Parsimoni have announced a joint project to develop an advanced platform for in-orbit software deployment, combining OHB Hellas’ Orbital HPC hardware solution with the Parsimoni Satellite App Store – powered by SpaceOS.

The collaboration brings together two complementary technologies to create a flexible, secure, and high-performance solution for next-generation space missions. SpaceOS is the first standard operating system designed specifically for securely hosting and managing shared software payloads in orbit, enabling multiple applications with strong isolation, security, and efficient resource utilization. When integrated with the OHB Hellas Orbital HPC, the joint solution provides a robust foundation for scalable and reusable in-orbit software services.

The first commercially offered solution will combine Parsimoni’s App Store project (developed with the support of ESA) and the OHB Versal Orbital HPC, and will be offered in conjunction with the OHB Fire and Cloud Detection apps.

Due to its high level of security, flexibility, and efficiency, the joint solution is ideally suited to protecting Europe. It enables mission operators to deploy, update, and manage software applications in orbit while reducing development effort and mission risk, built on a Zero Trust architecture that includes CCSDS/SLDS, PQC, and formal verification.

This joint project reflects a shared vision to enable more capable, secure, and adaptable space systems, supporting the growing demand for software-defined satellites and in-orbit services.
