SATEXPERT: a knowledge-based system for spacecraft control

Abstract The primary target of the SATEXPERT project is the development and the marketing of a family of products which is intended to extend the classical functionalities of a satellite control center (SCC). These products are built upon a source description of all satellite related knowledge in order to assure the consistency of information that SATEXPERT has to exploit in the operating phase. Therefore, a modeling language was defined allowing the experts to express satellite knowledge in a simple and suitable manner. The main products concern the satellite survey and control including diagnosis and manoeuvre performance. In particular, SATEXPERT will be able to detect and diagnose any space segment anomaly and subsequently perform the adequate reconfiguration operation. SATEXPERT will offer other capabilities during the satellite design, manufacturing and operational phases such as: • satellite design cross-check and validation, interfaces control (electric, TM/TC lists, …), • full satellite dynamic simulation, • generation and validation of the satellite operational documentation, • deep analysis of the on-board anomalies.
