GameSim is developing a framework, Validate, to detect synthetic environment correlation and integrity errors realized in military training systems. Validate automatically verifies correlation and correctness of new and networked training simulation environments to ensure a fair fight between networked participants. Validate provides a means to test correlation between any combination of source datasets, including NAVAIR Portable Source Initiative (NPSI) and run-time systems, including image generators (IG). GameSim provides game development services and expertise in synthetic environment design, development, and integration. GameSim developed a near real-time capability to import and fuse geospatial datasets, and has published extensive research in advanced M&S techniques. Validate’s prototype establishes design requirements and demonstrates the efficacy of a validation framework suitable for employment by training systems.
