README

This repo holds the physical design files for the:

 Radiation Tolerant Internal Housekeeping Unit (RT-IHU)

The RT-IHU was conceived as a successor to the Fox-series IHU flight computer. It aims tp increase reliability in higher Earth orbits where a harsher radiation environment might cause early failure of the "legacy" IHU design.
