ABSTRACT
The purpose of this communication is to review the applications of prognosis and health monitoring in satellite systems. It provides an insight into the problematic of using housekeeping information for prognosis and health monitoring. This challenge is particularly relevant in the spatial domain as it relates to operations, service removal with de-orbiting with respect to the LOS (Law on Space Operations) or the kick-off of new programs. In addition to the decision-making aspect, it relates to the diagnosis (identification of the state of the system) and prognosis (future degradation assessment and residual lifetime).
