Abstract

A reconnaissance/surveillance system for remote viewing of a selected location while providing a standoff distance from the selected location for personnel controlling the reconnaissance/surveillance system includes a remote controlled underwater vehicle and a delivery vehicle formed to deliver the remote controlled underwater vehicle to an underwater deployment position. An operator control console in the delivery vehicle is connected to the remote controlled underwater vehicle via a fiber optic communications link. A battery powered propulsion apparatus moves the remote controlled underwater vehicle through water to a viewing station under control of the operator control console. The remote controlled underwater vehicle includes sensing apparatus that provides signals that the operator control console uses to navigate the remote controlled underwater vehicle to the viewing station. The remote controlled underwater vehicle carries imaging apparatus arranged to form an image of an object at the selected location and transmit the image to the operator control console. The remote controlled underwater vehicle may also include a laser target designation system.

Claims

1. A reconnaissance/surveillance system for remote viewing of a selected location while providing a standoff distance from the selected location for personnel controlling the reconnaissance/surveillance system, comprising:

an underwater delivery vehicle that includes an operator control console;

a plurality of remotely controlled underwater vehicles mounted to the underwater delivery vehicle, each of the remotely controlled underwater vehicles including;

a propulsion system;

a telescoping mast that operates under the control of the operator control console;

a global positioning system module mounted to the telescoping mast for providing position data to the operator control console;

a camera mounted to the mast for forming an image of the selected location; and

a laser target designation module mounted to the telescoping mast and arranged to designate the selected location as a target;

a communications link connected between the operator control console and the remote controlled underwater vehicles, the operator control console being arranged to provide control signals via the communications link for deploying a selected one of the remotely controlled underwater vehicles from the delivery vehicle and controlling its propulsion system to transit it to a viewing station for performing a selected mission.

2. The reconnaissance/surveillance system of claim 1, wherein each of the remotely controlled underwater vehicles further comprises:

a sonar module arranged to provide sonar images from the remotely controlled underwater vehicle to the operator control console;

a non-visible light source;

an underwater camera arranged to form images of object illuminated by the non-visible light source.

3. A reconnaissance/surveillance system for remote viewing of a selected location while providing a standoff distance from the selected location for personnel controlling the reconnaissance/surveillance system, comprising:

a remote controlled underwater vehicle;

a delivery vehicle formed to deliver the remote controlled underwater vehicle to an underwater deployment position;

an operator control console in the delivery vehicle connected to the remote controlled underwater vehicle via a communications link;

propulsion apparatus for moving the remote controlled underwater vehicle through water to a viewing station under control of the operator control console; and

an imaging system mounted in the remote controlled underwater vehicle and arranged to form an image of an object at the selected location, the imaging system comprising a subsurface camera arranged to form images using non-visible light, a telescoping mast arranged to extend above the water surface and a surface camera mounted to an upper portion of the telescoping mast.

4. The reconnaissance/surveillance system of claim 3 further comprising a laser target designation module mounted to the mast and arranged to designate the selected location as a target.

7. The reconnaissance/surveillance system of claim 3 wherein the propulsion apparatus comprises a battery-powered horizontal motor for moving the remote controlled underwater vehicle through water to the viewing station and a vertical thruster for controlling the depth of the remote controlled underwater vehicle.

5. The reconnaissance/surveillance system of 3 wherein the communications link comprises a fiber optic cable arranged to transmit control signals and data between the operator control console and the remote controlled underwater vehicle.

6. The reconnaissance/surveillance system of claim 5 further comprising a global positioning system module mounted to the telescoping mast, the global positioning system module being arranged to provide position data for the remote underwater vehicle to the operator control console while the remote controlled underwater vehicle is in transit from the delivery vehicle to the viewing station.
