Radiation Hardened ARM Micro Controller Module, Phase I

Every CubeSat design is different with different requirements. However the number of similarities between CubeSat designs is greater than between any two larger spacecraft. Leveraging these similarities and by applying a modular design approach we can develop a small family of motherboards that can fulfill the needs of any CubeSat mission. The computing elements of a 1-3U motherboard and a 6U motherboard are the same. The differences between these CubeSat bus architectures exist outside the computing element. Thus, we can move the computing elements off of the motherboard and into a self-contained Compute Module (CM). The CM contains all the elements needed for a self-contained computer. The CM is attached to an Application Specific Daughter Card (ASDC). Together the CM and ASDC provide the capabilities needed for a specific task. This standard module will consist of a physical form factor, electrical connections and design specifications for the ASDC. The initial Compute Module (CM) design specifications will utilize SST' modified ARM® Cortex®-M0 microcontroller, motherboard for the 1-3U and a 6U CubeSat bus configuration. More »
