Many fielded weapon systems contain onboard fire control measures to accurately aim the weapon at a predetermined target. Often, these onboard systems are designed with proprietary interfaces and message formats, making the integration of new sensors or data sources costly and time consuming. As fire control systems become ubiquitous, the need for robust, open software architectures arises. Furthermore, significant improvements can be made to existing target location solutions that allow the deployment of non-designated, precision-guided munitions. Studies in distributed sensors have shown that they can be a simple, cost effective solution to enhance target accuracy. IAI is working to develop FUSEON, an open source framework and library capable of target detection and tracking, using data from distributed sensor sources. FUSEON will enable flexible integration of sensors and system development efforts. The FUSEON architecture includes four processing elements comprised of translation, triangulation, correction, and prioritization, which will interact through a common storage element where the different types of data structures can be maintained for flexible interaction. Each of these data structures will have a defined schema, flexible enough to accommodate different sensors and algorithms. This integrated, single-solution package will allow smooth and seamless integration between legacy systems and new technologies.
