Guidance, Navigation, and Control (GN&C) systems take data from the environment to create a mathematical representation of the system state. The system’s guidance solution is then determined from this navigation solution and is typically a minimization of some objective weight function, J. This objective function is a time, cost, weight, or other physically realizable quantity. In this paper we show a method to create a guidance solution based upon system risk for a system’s goal. The methodology presented uses a goal to create a situation. The situation assessment creates a situation model whose risk can be determined. The projection of this into the future then creates a trajectory for the system to follow. A simulation of using nautical vessels is shown and compared to traditional optimization methods.
