This presentation focuses on ARC's avionics design approach using Commercial Off-The-Shelf (COTS) parts for high-risk, high-reward missions. Examples of ARC's past missions in small spacecraft, nano-satellites, and Class D payloads are highlighted, emphasizing the benefits of COTS, such as wider selections, faster development schedules, and lower costs. The challenges and limitations of traditional Qualified Parts List (QPL) approaches are discussed, along with observations from ARC missions, which show that design and workmanship issues are more significant than component failures. Mitigations for radiation risks associated with COTS are proposed, emphasizing risk awareness, proper software and hardware design, and careful parts selection. The success of ARC's 30+ projects using COTS over the past 17 years underscores its viability for high-risk missions.
