The CubeSat platform provides a unique challenge for flight software design due to the incredible size and power constraints. A number of tradeoffs must be made to balance effectiveness, fault tolerance, and cost. These basic requirements have been combined with the lessons learned from Cal Poly’s past 8-bit avionics system to design a significant revision based around a 32-bit microprocessor running Linux. This work analyzes both generations of avionics design, including a discussion of major design principles that are relevant to other CubeSat missions.
