MIDS LVT is communication equipment mounted with Link-16-based weapon systems to provide the Link-16 operating environment between weapon systems. Currently, the military operates the MIDS LVT BU1, but it will be changed to the BU2 and JTRS according to the performance improvement. The communication interface, message data format, and message composition of the MIDS LVT are different depending on the platform family (BU1/BU2/JTRS) and type (A,D,J). In this paper, we propose a framework based emulator design and implementation method that considers the MIDS LVT platform extension to improve these problems. In consideration of the quality attributes of the sw architecture, we designed a common based framework for modifiability, reusability, and extensibility. The MIDS LVT emulator comprises the MIDS LVT emulator processing, link interface processing, and monitoring tool. The MIDS LVT emulator was implemented by deriving and improving functions through the analysis of the functions of the previously developed overseas tools. Through the development of the MIDS LVT emulator, it can be used to develop and verify the developed Link-16 host system.

Dynamic models are important elements in the process of developing weapon system simulators based on the Defense Modeling and Simulation(DM&S). Also, the model’s accuracy according to the purpose of the DM&S is a very important factor, therefore the modules of the dynamic models should be modified to satisfy required model’s fidelity. The objective of this study is to design a structure of ModelAgent that can efficiently develop and manage the dynamic models. The ModelAgent is designed not only to improve reuse by encapsulating modules using object oriented language but also to be scalable to accommodate a variety of requirements by applying design patterns. Also, the ModelAgent is designed to provide a common interface that enhances portability in the development of dynamic models.
