Formal verification of spacecraft control programs

Last February I spent two weeks in Vienna, visiting Jakob Lechner and RUAG Space Austria, a company developing components for space missions. Jakob and his colleagues designed a specialised processing core called REDFIN (REDuced instruction set for Fixed-point & INteger arithmetic) for executing simple spacecraft control tasks, such as satellite antenna pointing. During the visit I implemented a prototype of a formal verification framework to support the development of REDFIN programs. Afterwards I was quite busy with my other projects, but my PhD student Georgy Lukyanov helped to further improve the prototype.

Jakob, Georgy and I have just submitted a conference paper describing the REDFIN core and the verification framework.┬áPlease have a look and let us know what you think. This will be a timely read after yesterday’s exciting SpaceX launch.
