Core Flight Executive Software Radiation Mitigation Study

Metadata Updated: July 17, 2020

The reliability of SmallSat / CubeSat missions may be increased by using software[HTML_REMOVED]radiation mitigation for single event upsets (SEUs). Implementing protection in software[HTML_REMOVED]results in a lower level of tolerance than traditional hardware techniques, but hardware[HTML_REMOVED]costs and power requirements are kept to a minimum by taking advantage of nonredundant commodity hardware. This work[HTML_REMOVED]will extend NASA[HTML_REMOVED]s Core Flight Executive[HTML_REMOVED](cFE) to provide software based protection and evaluate the results so that informed decisions can be made about such trade-offs.The project objectives are to answer the following questions about software radiation mitigation techniques applied to NASA[HTML_REMOVED]s Core Flight Executive (cFE):[HTML_REMOVED] How much can the occurrence of failures due to SEUs be reduced?[HTML_REMOVED] What were the costs in terms of processor overhead?[HTML_REMOVED] What are the impacts on normal cFE application development?To answer these questions, this project will incorporate software radiation mitigation[HTML_REMOVED]into cFE for an example CubeSat application. The primary protection mechanism investigated will be[HTML_REMOVED]scalable modular redundancy of software components (applications). Scalable modular[HTML_REMOVED]redundancy will be non-intrusive for cFE application developers and allow the level of[HTML_REMOVED]redundancy to be adjusted as needed. Other techniques, such as source level approaches,[HTML_REMOVED]may be employed for cFE itself if testing reveals potential reliability gains.
