This paper focuses on verification of spacecraft SW for the electrical power subsystem (EPS) for a particular geostationary satellite. Choosing an appropriate topology is a key point in the process of electrical power subsystem design. Concepts of energy transfer. i.e. Direct Energy Transfer (DET) and Peak Power Tracker (PPT) are discussed. The EPS spacecraft SW verification is based on the functionality...
Functional and performance testing of critical space software is a very complex task since demanding quality requirements have to be fulfilled. In order to avoid any serious project delay and to preserve the product quality it is necessary to focus on test process definition, testing automation, testing tools, and standardization since the early phases of the project. This paper proposes a testing...
FDIR functionalities are investigated since the very beginning of a space mission and play a relevant role in the definition of its autonomy, reliability and availability objectives. In this paper, an analytical methodology derived from the Timed Failure Propagation Graph (ETFPG) is proposed. TPFG is a causal model that captures the temporal aspects of failure propagation in a wide variety of engineering...
