The Phase I SBIR effort demonstrated GPS based autonomous waypoint navigation of an Unmanned Surface Vehicle (USV) used as a target in live firing exercises. Waypoints were inserted via an Over The Horizon (OTH) satellite based communication link. Another endeavor indicates that a USV can also serve as a tactical target to divert incoming missiles, i.e., act as a decoy. All these target functions would benefit from the use of a common, ship deployable USV, configured as discussed herein. This Phase II effort will provide a retrofit kit to configure existing Target USVs with an autonomous navigaitonal capability. This retrofit kit, with minor additions, can also convert the workboat currently deployed on modern American/Canadian warships into a USV suitable for tactical, at sea training, and live firing exercises.
