3.9 Summary of Technology Standards for the FRM
The airborne reconnaissance functional reference model (FRM) provides a common framework for defining the scope and functional makeup of airborne reconnaissance systems. The FRM is critical for selecting standards and effectively depicting where they must be applied in the overall framework. The FRM is based on the functional model developed by the Joint Airborne SIGINT Architecture (JASA) Working Group and approved by the Defense Airborne Reconnaissance Steering Committee (DARSC). The FRM incorporates additional functions found in IMINT and MASINT systems required to satisfy warfighter requirements, more explicit mission planning and control functions, and expanded functions for integrating airborne reconnaissance with warfighter and other C4I systems (e.g., command and control systems, air tasking, and collection management).
