Standard Guidance, Navigation, and Control (GN&C) systems take state data from a navigation system and create a trajectory that minimizes some a-priori determined cost function. These cost functions are typically time, money, weight, or any general physically realizable quantity. Previous work has been done to show the effectiveness of using risk as the sole objective function. However, this previous work used Poisson distributions and historical estimates to achieve this goal. In this talk we present the SRA (Situation Risk Assessment) method contained within the intelligent collision avoidance (iSC) platform. The SRA method uses data clustering, and pattern re-cognition to create a historically based estimate of guidance probabilities. These are then used in data driven, dynamic models to create the fu-ture probability fields of the situation. This probability, along with the other agent’s goals and objectives, are then used to create a minimum risk guidance solution nautical situations and for air traffic.
