An unmanned underwater vehicle (UUV) is equipped with a GPS, heading sensor, depth and altitude sensors, and an acoustic navigation system. The UUV is deployed in the vicinity of the target location and releases an acoustic transponder (beacon). Using the acoustic navigation system with the GPS reference, the UUV conducts a survey to determine the horizontal location of the beacon on the seafloor and calculates a relative position between the beacon and the target. The UUV can plan a travel path allowing it to relocate the target, using the beacon as a navigation aid. The UUV can submerge to target depth and search for the target using a forward looking sensor. Once the target is acquired on the sensor, the UUV can home to the target.

Self surveying navigation system

An unmanned system performs inspection, identification and/or neutralization of underwater objects. An unmanned vehicle that operates at a water's surface stows underwater crawling and/or swimming vehicles that can operate underneath a water's surface. A winch associated with each robotic vehicle is mounted on the unmanned vehicle. An electro-mechanical tether electrically and mechanically couples a corresponding robotic vehicle to the unmanned vehicle, and is mechanically coupled to a corresponding winch for control of the paying out and reeling in thereof.
