1. A method of operation of a navigation system comprising: determining detected information for representing a maneuverable object capable of self-propelled physical movement or displacement, detected using a device; identifying a directional portion based on the detected information for representing directional portion controlling an object travel vector of the maneuverable object; and calculating with a control circuit an estimated trajectory profile based on the directional portion for predicting movement of the maneuverable object, wherein the estimated trajectory profile includes a reference measurement, and wherein the reference measurement is calculated based on an angle relative to a surface of the maneuverable object.
