Abstract

CubeSats require robust OBDH solutions in harsh environments. The Demoiselle OBC, featuring a radiation-tolerant APSoC and layered FSW, supports reuse, in-orbit updates, and secure operations. To be validated through ITASAT2 and SelenITA, it ensures fault tolerance, flexibility, and compatibility with emerging technologies. This architecture establishes a foundation for long-lasting, scalable OBDH systems in future Brazilian CubeSat missions, ensuring long-term reliability and adaptability.
