N2 - The differences of onboard faults characteristics and severity result in different models, methods and interfaces of fault diagnosis. Thus, FDIR (Fault Discovery, Identification and Recovery) systems usually use a hierarchical architecture in centralized or distributed styles. It is difficult for the centralized FDIR to guarantee the timeliness and coverage of fault diagnosis simultaneously, and the distributed one would bring safety problems. Both of them only focus on the health states of spacecrafts, while not considering its own reliability and reusability. Taking advantage of the above two, the architecture proposed by this paper keeps synthetic views of the spacecraft health states at higher levels and distributes local FDIR at lower levels to improve the timeliness and coverage of fault diagnosis simultaneously, which is based on the hierarchical architecture of spacecrafts and fault severity levels. To ensure the safety and reliability of the FDIR system, a highly decoupled runtime model is proposed. To improve the reusability of the architecture, a unified FDIR model is proposed, which includes hierarchical programming interfaces, etc.
