Abstract

A reconnaissance system and method utilizes an unmanned surface vehicle (USV) and at least one micro-aerial vehicle (MAV). The MAV, equipped for unmanned flight after a launch thereof, is mounted on the USV. Each MAV has onboard wireless communications coupled to an onboard video surveillance system. Each MAV launched into the air collects video data using its video surveillance and transmits the video data using its wireless communications.

Claims

1. A reconnaissance system, comprising:

an unmanned surface vehicle (USV) capable of navigated movement on an earth surface;

at least one micro-aerial vehicle (MAV) equipped for unmanned flight after a launch thereof, each said MAV mounted on said USV, each said MAV having wireless communication means coupled to video surveillance means; and

launching means mounted on said USV for launching each said MAV into the air, wherein each said MAV so-launched into the air collects video data using said video surveillance means and transmits said video data using said wireless communication means.

2. A reconnaissance system as in claim 1 wherein each said MAV includes a motor for in-air propulsion, and wherein said reconnaissance system further comprises a hardwired link coupling said USV to said motor when said MAV is mounted on said USV, wherein said motor is started via a command received from said USV and wherein said hardwired link is uncoupled from said motor when said MAV is launched into the air.

3. A reconnaissance system as in claim 1 wherein each said MAV further comprises:

navigation means for generating in-air positions of said MAV; and

flight control means coupled to said navigation means for steering said MAV using said in-air positions.

4. A reconnaissance system as in claim 1 wherein said wireless communication means comprises:

a first RF transceiver for communication with said USV; and

a second RF transceiver for communication with a remote location that is at least one of an in-air location, an on-the-water location and an on-the-ground location.

5. A reconnaissance system as in claim 1 wherein said USV includes pre-programmed means for controlling said navigated movement in an autonomous fashion.

6. A reconnaissance system as in claim 1 wherein said USV includes means for receiving instructions from a location that is remote with respect to said USV wherein said instructions govern said navigated movement.

7. A reconnaissance system, comprising:

an unmanned surface vehicle (USV) having means for controlling movement thereof on an earth surface;

a plurality of micro-aerial vehicles (MAVs) onboard said USV, each said plurality of MAVs having flight control means, radio frequency (RF) communication means and video surveillance means mounted thereon;

launching means mounted on said USV for launching each of said plurality of MAVs into the air; and

launch control means mounted on said USV and coupled to said launching means and each of said plurality of MAVs, wherein said launch control means activates said flight control means, said video surveillance means and said RF communication means for a corresponding one of said plurality of MAVs just prior to the launch thereof, wherein each of said plurality of MAVs so-launched into the air collects video data using said video surveillance means and transmits said video data using said RF communication means.

8. A reconnaissance system as in claim 7 wherein said USV further includes wireless communication means mounted thereon for relaying said video data so-transmitted from each of said plurality of MAVs to a remote location.

9. A reconnaissance system as in claim 8 wherein said wireless communication means uses at least one of satellite-based communications, RF-based communications and acoustic-based communications.

10. A reconnaissance system as in claim 7 wherein said means for controlling movement operates autonomously.

11. A reconnaissance system as in claim 7 wherein said means for controlling movement is operated from a location that is remote with respect to said USV.

12. A method of reconnoitering, comprising the steps of:

providing an unmanned surface vehicle (USV) capable of navigated movement on an earth surface;

providing a plurality of micro-aerial vehicles (MAVs) onboard said USV, each said plurality of MAVs having flight control means, radio frequency (RF) communication means and video surveillance means mounted thereon;

activating said flight control means of a corresponding one of said plurality of MAVs;

launching said corresponding one into the air;

activating said RF communication means and said video surveillance means for said corresponding one so-launched into the air;

collecting video data using said video surveillance means so-activated; and

transmitting said video data using said RF communication means so-activated.

13. A method according to claim 12 wherein said USV is equipped for wireless communication, and wherein said method further comprises the steps of:

receiving said video data transmitted from said corresponding one of said plurality of MAVs; and

re-transmitting said video data using said wireless communication to a location remote with respect to said USV.

14. A method according to claim 13 wherein said step of re-transmitting uses at least one of satellite-based communications, RF-based communications and acoustic-based communications.

15. A method according to claim 12 further comprising the step of remotely controlling said navigated movement of said USV.

16. A method according to claim 15 further comprising the step of remotely controlling said step of activating said flight control means and said step of launching.
