The Global Broadcast Service utilizes commercial direct broadcast satellite technology tailored specifically for military application. With this service, the military directly addresses oversubscribed communication paths and introduces a quantum leap in information dissemination. However, the potential for information overload comes with the ability of this service to readily deliver multi-megabit per second data. Therefore, to make the Global Broadcast Service a value-added addition to command and control, an information management process must be deployed concurrently. This project builds a Global Broadcast Service model (using Extend) to provide a tool to analyze information dissemination management. Recent technologies such as asymmetric networking and automated radio frequency management are integrated into the model. In this thesis, asymmetric networking is equated to Global Broadcast Service "reach back," and automated radio- frequency management is equated to the functionality of the "Automated Digital Network System." Using a simulation, an initial analysis of various reach back channels is provided. The resulting model and analysis serve as a foundation for future process development for Global Broadcast Service Information Dissemination Management.
