Integrating Live, Virtual and Constructive entities to support military training is the ultimate goal of a Synthetic Training Environment (STE). LVC training incorporates geographically distributed real time simulation systems, virtual simulators, and live training devices into a single shared virtual environment to maximize immersive training experiences. Currently LVC interoperability relies on Distributed Interoperability Simulation (DIS) protocols and High Level Architecture (HLA) for communications amongst training systems. With this industry standard, each training device must be able to communicate across the network using DIS protocols or HLA FOMs. Integrated Sensor Architecture (ISA) was developed to support Army ground tactical combat by Army’s Night Vision and Electronic Sensors Directorate (NVESD). Its architecture was designed to manage the sensor systems of systems (SoS) as well as the distribution of sensor data. ISA brings together a collection of live sensors within an area of operation so they can communicate without requiring physical integration with a set of well-defined protocols in place to ensure interoperability when additional sensors come online to the network. Although ISA was designed to work in the tactical environment, its capability of allowing different sensors to dynamically interact with each other is also very desirable for distributed realtime simulation and training exercise. Our preliminary research shows that in order to bring ISA into the distributed simulation domain, the most important step is to make its communication protocols DIS compliant. During the prototyping of an interface that converts ISA sensor data to DIS EntityState PDU, we realized the need for a full complement of DIS sensor message representation. We believe the sensor data can be represented in a new type of DIS PDU, by reusing some ISA classification scheme of capabilities, and having the protocol standardized would enable tactical sensors to be part of the virtual training world.
