Abstract: Resource homeostasis is very important in constellation satellite communication system In order to fulfill the communication task efficiently, macroscopical economic theory was applied to resource homeostasis. A resource homeostasis mathematic model based on dummy factory was presented, and capability evaluation system, consummation evaluanon system and cost evaluation system were discussed in detail to improve the effectiveness of resource usage evaluation, whose feasibility and validity were proved with the sample of the evaluation of Iridium 13y building and solving the resource homeostasis modcl,rclationship between inner and exterior circumstances of the system, users' requirements, resource usage and time and space was abtained,and the rectuirements to reach pareto optimality were also gained. Research on the resource homeostasis lays the foundation for solving resource allocation problem in constellation satellite communication system.

Key words: Constellation satellite,Resource homeostasis,Dummy factory,Pareto optimality
