Adopting a model-based approach for satellite operations' diagnosis

Abstract : The diagnosis procedure in satellite operations is constrained by strict time limits. If a failure occurs, operators must be efficient and proactive, as diagnosis must be completed within the smallest number of visibility windows (pass duration over the ground station which are usually very short and separated by long periods where the ground cannot communicate with the satellite). Improving the diagnosis procedure and tools, time and precision-wise, is therefore essential. The proposal presented in this position paper is to provide the operators with operation-dedicated models to help them in reacting quickly and in finding a suitable repair solution as fast as possible. These models will gather system architecture, functional and dysfunctional data taken from system engineering and safety analysis models. The paper presents the framework of the proposed solution and discusses different implementation options.
