In the space field, the ever growing complexity of satellites led to a significant increase in the amount of data to be processed from the ground, and to a critical need to react safely in case of contingency. Moreover, since the life cycle of satellites of the new generation often exceeds 10 years, maintaining a full team of trained engineers and experts along this period of time is too constraining and costly. In this context work on specifying and prototyping what will be the new family of ground based centers for automated satellite control was undertaken. A survey of the techniques involved in these systems with specific focus on the decision making aspect is presented. Knowledge based techniqes are shown to be a natural answer to the main requirements of the problems and, through the reactivity question, the concepts of the procedural command module are introduced. A demonstrator implementing a procedural expert system coupled to a satellite simulator is described.
