Abstract
Fault management is one of the key technologies that enable distributed and disaggregated mission architectures wherein multiple vehicles work cooperatively and autonomously in a cluster or formation, a typical mission concept involving small satellites. In this paper, we describe a software architecture, called Separable Architecture for Fault Isolation and Recovery (SAFIR), which addresses fault management for these types of missions. Although SAFIR is applicable to any system of systems, this paper demonstrates SAFIR for a cluster of spacecraft. The resulting fault detection, isolation, and recovery benefits from the SAFIR architecture because it is robust to intermittent communication and highly modular. The SAFIR software has been developed as apps for the Core Flight System (cFS) and has been demonstrated successfully on representative hardware using a high fidelity simulation of spacecraft in low earth orbit.
