Multiple Interface Modeling and Simulation Application (MIMoSA)

Combat systems consist of a diverse mix of sensors, weapons, control systems, and display subsystems operating in a federated fashion. Typically, subsystems maintain high fidelity synthetic simulations for their sensor level interfaces; however, simulations of control system and weapon system interfaces for test, certification and training are of limited fidelity, allowing for syntactic, semantic, and timing mismatches. In addition, existing tools for modeling and simulating these interfaces are difficult to use, are too broad in scope, and require lengthy development times. Architecture Technology Corporation will develop the Multiple Interface Modeling and Simulation Application (MIMoSA), which uses high level architecture (HLA) to provide high-fidelity interface modeling and simulation capabilities to developers of Navy combat systems. MIMoSA captures interfaces between platform combat system elements, creates object code for federate models, and uses a program called the Sequencer to automatically feed synchronous and asynchronous communication data to an HLA simulation which can validate interface transactions. The functionality developed will allow developers to test the semantics and syntax of communications between federates, to employ effectively and efficiently user-defined algorithms for federate interaction, to support synchronization with other simulations, and to prevent changes and additions from impacting simulation fidelity.
