On-Board Computers (OBC) – Built for Adaptive Avionics
Fox2Space On-Board Computers are built from the ground up on open standards as ideal platforms for Adaptive Avionics. They are reliable, efficient, fault-tolerant, and low-power, scaling from SmallSats down to CubeSats as small as 2U.
Our OBCs lower the barrier to achieving true fault tolerance. By using current, well-known platforms and architectures that most young engineers already know before they get their first job, even novice engineers can quickly, confidently, and productively deploy stable, robust, and verifiable systems—without years of specialized avionics training.
Product Versions
Feather
Easy to work with, efficient, flexible, light, but truly fault tolerant.
Perfect for small CubeSats flying light payloads in tech-demo, educational, or scientific missions — where ease of handling and rapid development cycles are essential. Fox2Space’s founders used to build CubeSats and would have loved to be able to buy something like Feather back then to give us wings.
Advanced
Flexible, reliable, high-bandwidth, and high-throughput OBC for demanding missions such as Earth observation, telecom, and advanced science.
Handles multiple high-performance payloads with ease, yet is easy to work with and efficient to support fast paced missions development cycles with confidence and a solution that you can rely on.
Robust
Everything in Advanced, plus:
- GaN-based fault-tolerant, radiation-hardened power train
- Radiation-tolerant space-grade FPGA option
- Support for advanced processing setups including the use of ARM Cortex-A cores ARMv8 instead of RISCV
- Optimized for high-radiation and highest priority mission where flying known good industrial/extended/mil-grade FPGAs with low Risk Acceptance is just not an option anymore
Performance
Our most advanced, high-reliability, high-performance OBC for payload and platform control in missions where peak reliability and top-end performance are both mandatory, and neither can be compromised on, while also offering drastically lower component level complexity due to the latest advances in semiconductor design and manufacturing.
Common Features & Customization
- Form Factor: LibreCube Standard (95.89 × 90.17 mm)

- Mission Fit: Specifications vary per mission—customers approve the final configuration before production
Lifetime Modeling — Not Reliability Guesstimates
Fault tolerance is built at the system level, fully integrated into hardware and software, enabling predictable and quantifiable mission lifetime assurance based on your exact mission profile.
Our OBCs support lifetime modeling using the same engineering simulation techniques applied in astronomy, physics, and mechanical engineering—far beyond probability-based estimates.
Supply Chain Resilience — Designed for Change
We understand that parts availability, tariffs, and international trade constraints can disrupt mission planning. That’s why our OBCs are built on a heavily modular, unified architecture where key components can be freely substituted to match customer preferences or adapt to shifting global supply conditions.
Whether it’s vendor changes, tariff restrictions, or component obsolescence, our design ensures your mission is never locked to a single supplier. Components can be swapped without redesigning the entire system, ensuring uninterrupted manufacturing and long-term maintainability.
This same flexibility allows fleet-wide standardization across spacecraft, simplifying logistics, training, and maintenance—while lowering costs.
