In this paper, we present a proof-of-concept prototype system created in an applied research and development effort at Southwest Research Institute. The Advanced Situational Awareness (ASA) Modeling and Visualization Environment is a response to the need for applications that improve the value and presentation of situational awareness information by leveraging the increased integration of sensors, Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR), and Electronic Warfare (EW) systems with networks in ground vehicles. The ongoing U.S. Army Vehicular Integration for C4ISR/EW Interoperability (VICTORY) initiative is providing the framework by which this integration of sensors and systems can be realized. By utilizing the VICTORY concepts and current specifications, the research team was able to develop an ASA system that provides: cross-vehicle reasoning, visualization of situation awareness (SA) data overlaid on video, and a mapping capability.
