Abstract
As the proliferation of small satellites continues at a staggering rate, so does the mission complexity and criticality of ensuring reliability throughout the satellite bus. Specifically, the command and data bus connecting subsystems within a small satellite can experience radiation-induced faults that potentially derail the satellite’s intended operation, necessitating architecture- and protocol-level fault management. This paper presents an innovative ”Resilient-by-design” communication bus that incorporates a dual-hot redundant architecture and an intelligent, adaptive protocol to coordinate messages and manage faults in an autonomous, self-recoverable manner.
