This article investigates the degradation and failure behavior of spacecraft electrical power subsystem (EPS) on orbit. First, this work provides updated statistical reliability and multi-state failure analyses of spacecraft EPS and its different constituents, namely the batteries, the power distribution, and the solar arrays. The EPS is shown to suffer from infant mortality and to be a major driver...
A statistical analysis of satellite Electrical Power Subsystem (EPS) failures is conducted in this paper, and of particular interest is the comparison of the failures between the EPS of LEO and GEO satellites. To investigate in more details the failure mechanisms of the EPS, we also analyze the failure data of four subsystems of the EPS: the Battery / Cell subsystem, the Electrical Distribution subsystem...
