On-board software
Critical software design for OBCs and DPUs based on ARM, LEON (SPARC) and RISC-V — bare-metal or RTOS-based.
Software that space can rely on
Engineers behind critical on-board software for flagship science missions and commercial satellites — rigorously verified, standards-compliant, flight-proven.
What we do
Software you can fly with confidence
We take responsibility for the full on-board software lifecycle — from requirements and model-based design to qualification — following rigorous ESA ECSS processes, so your mission saves time and risk.
Model-based engineering
MBSE toolchains and code generation with ESA TASTE, plus ASN.1/ACN data modelling for PUS-C TC/TM protocols.
QA & ISVV
Automated validation suites, code coverage on target and Independent Software Verification and Validation.
Payload computers
Payload control units (OBCUs) integrated with flight software — from scientific instruments to ISS experiments.
Products
Pre-qualified. Ready to integrate.
Reusable software components developed under ESA contracts and delivered with ECSS qualification data packs — with delta-qualification support for your hardware when you need it.
Flight software
SAVOIR Boot Software & BSP
SAVOIR-compliant bootloader and Board Support Packages, pre-qualified to ECSS Criticality B. Integrate in weeks instead of developing and qualifying from scratch.
