With the development and growing applications of information technology,the coupling and dependency of systems in space TTC(Tracking,Telemetry and Command)networks is becoming more and more intense.The use of the analysis method for interdependent networks is proposed to enhance the robustness of TTC networks with interdependent characteristics.Information in space TTC networks is categorized into interdependent data information and control information based on the role of information in the networks following analysis of the stability of cascade failure process of interdependent networks for space TTC networks.The robustness of space TTC networks in different control information modes is studied for targeted attacks on single-sided networks.A method is proposed for building a robust and high efficiency TTC network.Simulation results show that the robustness of a space TTC network can be effectively protected by rational planning and reducing the size of control information in case of attacks on data information.
