1. An automated method for reducing simulation prediction error comprising the steps of: estimating, by an electronic computer, a future position of an underwater vehicle based on a forecast ocean current, a commanded heading and speed of the vehicle, a position of the vehicle at a specific time while submerged, and a dynamic compensation factor; comparing, by an electronic computer, the future position compared to an expected position; revising, by an electronic computer, the dynamic compensation factor based on the step of comparing; and reducing the simulation prediction error based on the revised dynamic compensation factor.
