A modular payload designed to collect on-orbit radiation-response data has been developed to validate terrestrial predictions for microelectronics in space. The project aims to refine radiation error-rate models to improve confidence in deploying advanced microelectronics in radiation-rich environments.
Key takeaways
The IUB-SAT-1 payload integrates IU’s RadFX-IC and commercial SRAMs to collect on-orbit data.
The project addresses the lack of validation for terrestrial radiation predictions once devices are deployed in space.
The data collected aims to refine radiation error-rate models for advanced microelectronics.
The payload was designed by IU CREATE and The Radiation Team.

Ms to address the risks posed by the complex and time-varying radiation environment in space.
The project seeks to bridge a gap in space technology where terrestrial radiation sources are used to characterize devices before missions, but the resulting in-orbit error rate predictions are rarely validated during deployment. By using well-characterized terrestrial radiation responses within the IUB-SAT-1 payload, researchers aim to refine radiation error-rate models. This work is intended to improve confidence when deploying advanced microelectronics into radiation-rich space environments.
