Autonomous systems for satellites planning usually utilize a knowledge base to generate flight operations plans. This knowledge base contains information that can be obtained via contributions from several experts. In a satellite control system, the knowledge base includes information about: components of the satellite, environment where the satellite operates, actions that the satellite can execute, and the effects of these actions. In planning, it is expected that the scheduling of routine actions is executed so that the satellite is operated in the best possible way. Satellite operations planning may benefit from simulators built specifically to simulate operational actions and situations before execution. This ensures that errors in planning are detected and corrected, preventing onboard failures. The objective of this paper is to show the strategies that are being applied at INPE (Brazilian National Institute for Space Research) for implementation of an automated planning system for future missions. These strategies range from the creation of a knowledge base for storage the history of all flight operations plans, up to the creation of a simulator to validate these plans, so that the satellites health is not compromised.
