Integrated Avionics Unit
Key Features
The LuxSpace Integrated Avionics Unit (IAU) is a next-generation avionics solution that merges platform functions like On-Board Computer (OBC), Telemetry and Telecommand as well as Remote Terminal functions with Payload functions like Payload Data Handling Unit (PDHU) into a single, modular unit.
- Modular & Scalable performance and dependability suitable for satellites >80 kg, from microsats to minisats and larger platforms. Supports a wide range of sensor interfaces through expandable processing modules.
- High Performance – Built around advanced ‘System-on-Chips’ technology, enabling demanding tasks such as real-time Earth observation image processing, data compression, and on-orbit AI applications.
- Multi-mission profile through function-agnostic architecture which can be reconfigured through software to support Earth observation, telecommunications, science, and defense missions.
- Radiation-Resilient – through up-screening and heritage based proprietary ruggedization of COTS components with integrated Fault Detection, Isolation and Recovery (FDIR).
- ESA Qualified – Tested and qualified under the Triton-X programme (TRL 8 in 2025, progressing to TRL 9 with flight heritage by 2026).
Benefits
- Reduced Complexity – Combines OBC, telecommunication and payload data handling in one unit, cutting mass, power, and volume as well as integration time at satellite level.
- Shorter Development Cycles – Ready-made, ESA-qualified unit reduces non-recurring engineering and accelerates mission timelines.
- Easy Onboarding – Board support package and low level device drivers available, “Ready to use” development kit that can be extended to full EM.
- Constellation-Ready – Designed for industrialized production at LuxSpace’s facilities in Luxembourg, with volume pricing available for constellation deployments.
Proven Heritage
The IAU builds on LuxSpace’s 15+ years flight heritage of avionics equipment and the wider OHB Group’s expertise. Its first in-orbit demonstration will be on a Triton-X Heavy mission, paving the way for adoption in a wide range of commercial, institutional, and defense programs.
