Fault Protection

Pattern

How does one handle fault protection in F Prime?

Rationale

Team recommended pattern.

Yes please! FDIR stuff is so open ended, having somewhere to start that's based on JPL heritage would be super valuable.

Depending on the project there are various implementations floating around. But when I was working full time at JPL I used the book "Patterns for Fault Tolerant Software" by Robert S. Hammer. I am not think it is in print anymore but you might find one for free on the internet. I do not know. It is very expensive on amazon see https://www.amazon.com/Patterns-Fault-Tolerant-Software-Wiley-ebook/dp/B00DXK33SK/ref=sr_1_1?crid=2SOISQ0OVE8Y7&dib=eyJ2IjoiMSJ9.MeMA_Ks6dxayK2sbxB5GoRboyDR7t1dD-dNQGuqiAV_xZjn7fg0g4NYjw5O7kb3gbznmqKG2nIWZpuNbUX0nVq3Pew1T4laTHxuvQskEqvk.cOXyVNlePOk0gRgzjmO2R_FM4iyJXqXLqgbKhr7rCk4&dib_tag=se&keywords=Patterns+for+fault+tolerant+software&qid=1741073504&sprefix=patterns+for+fault+tolerant+software%2Caps%2C128&sr=8-1#

Anyway the book explains pretty much every single FDIR architecture I had seen at JPL working on several flight projects. There is no code but it is all the concepts and who could develop a nice FDIR system from this book.

Personally I the FDIR concept is now a little dated since it really should be a bit more predictive and include some machine learning sort of estimation techniques. Just my thought.

Hope this helps.
