The qualitative analysis and comparison of commonly-used autonomous control architectures of Distributed Satellite Systems (DSS) are discussed. Based on it, a hybrid systematic hierarchical architectures model with two levels is put forward to fulfill autonomous cooperation demands of DSS under the dynamic and complicated uncertain circumstances. Furthmore, a novel agent model on satellite control architecture is outlined, and the components, functions and relationships of agents in the architecture are analyzed. It is designed for multi-satellites cooperation and satellite self-government, thus it has generality to a certain extent.
