Adaptive tactical navigation denouement

An overview is given of the adaptive tactical navigation (ATN) system, a laboratory prototype of a knowledge-based system which provides navigation system management and decision aiding for the next generation of tactical aircraft. The purpose of the ATN system is to manage a future multisensor navigation suite, dynamically selecting the best source of navigation information based on the current mission phase, mission goals, threat environment, and equipment availability. ATN encompasses functions as diverse as sensor data interpretation, diagnosis, and planning. The ATN system was developed and evaluated in a laboratory environment, followed by rehosting and evaluation in an F-16 cockpit simulation dome environment. Evaluation results indicate that operational deployment of a system using ATN technology would result in optimal use of navigation resources, reduced pilot workload, improved situational awareness, and intelligent navigation system failure detection and isolation. Collectively, these benefits provide significant improvement in mission effectiveness. Program results and lessons learned are presented
