Abstract

A communications system and method utilizes an unmanned surface vehicle (USV) capable of collecting data about an environment in which the USV resides. At least one micro-aerial vehicle (MAV), equipped for unmanned flight after a launch thereof, is mounted on the USV. Each MAV has onboard radio frequency (RF) communications. Each MAV launched into the air transmits the data collected by the USV using the MAV'"'"'s RF communications.

Claims

1. A communications system, comprising:

an unmanned surface vehicle (USV) capable of movement on an earth surface, said USV having data collection means for collecting data about an environment in which said USV resides;

at least one micro-aerial vehicle (MAV) equipped for unmanned flight after a launch thereof, said MAV mounted on said USV and having radio frequency (RF) communication means mounted thereon; and

launching means mounted on said USV for launching said MAV into the air, wherein said MAV so-launched into the air transmits said data using said RF communication means.

2. A communications system as in claim 1 wherein said USV further comprises an RF transceiver for transmitting said data to said RF communications means associated with said MAV so-launched.

3. A communications system as in claim 2 further comprising surveillance vehicles in the vicinity of said USV, each of said surveillance vehicles being equipped with means for transferring information therefrom to said USV wherein said information becomes at least a portion of said data so-collected by said USV.

4. A communications system as in claim 2 wherein said earth surface is a water surface, said USV further including acoustic communication means coupled to said RF transceiver, and said communications system further comprising unmanned underwater vehicles (UUVs) under the water surface and in the vicinity of said USV, each of said UUVs being equipped with an acoustic transmitter for transmitting information therefrom through the water to said acoustic communication means of said USV wherein said information becomes at least a portion of said data so-collected by said USV.

5. A communications system as in claim 2 further comprising surveillance vehicles in the vicinity of said USV, each of said surveillance vehicles being equipped with an RF transmitter for transmitting information therefrom to said RF transceiver of said USV wherein said information becomes at least a portion of said data so-collected by said USV.

6. A communications system as in claim 2 wherein said RF communications means comprises:

a first RF transceiver for two-way communication with said RF transceiver of said USV; and

a second RF transceiver for two-way communication with a location that is remote with respect to said USV, wherein said first RF transceiver and said second RF transceiver can operate simultaneously.

7. A communications system as in claim 1 wherein said MAV further includes data storage means coupled to said data collection means and to said RF communications means, wherein said data is transferred from said data collection means to said data storage means prior to launching said MAV and wherein, after launching said MAV, said data is transmitted from said data storage means associated with said MAV so-launched using said RF communication means associated with said MAV so-launched.

8. A method of communication between an unmanned surface vehicle (USV) and a location that is remote with respect to USV, comprising the steps of:

using said USV as a node for the collection of data;

providing at least one micro-aerial vehicle (MAV) on said USV, said MAV being equipped for unmanned flight after a launch thereof, said MAV having radio frequency (RF) communication means mounted thereon;

launching said MAV into the air from said USV; and

transmitting said data using said RF communication means on said MAV so-launched into the air.

9. A method according to claim 8 wherein said step of transmitting comprises the steps of:

providing an RF transceiver on said USV; and

transmitting said data to said RF communications means associated with said MAV so-launched into the air using said RF transceiver on said USV.

10. A method according to claim 9 further comprising the steps of:

providing surveillance vehicles in the vicinity of said USV, each of said surveillance vehicles being equipped with means for transmitting information therefrom; and

transmitting said information from each of said surveillance vehicles to said USV wherein said information becomes at least a portion of said data so-collected by said USV.

11. A method according to claim 9 wherein said earth surface is a water surface, said method further comprising the steps of:

providing said USV with acoustic communication means coupled to said RF transceiver;

providing unmanned underwater vehicles (UUVs) under the water surface and in the vicinity of said USV, each of said UUVs being equipped with an acoustic transmitter; and

transmitting information from each said acoustic transmitter through the water to said acoustic communication means of said USV wherein said information becomes at least a portion of said data so-collected by said USV.

12. A method according to claim 9 further comprising the steps of:

providing surveillance vehicles in the vicinity of said USV, each of said surveillance vehicles being equipped with an RF transmitter; and

transmitting information from each of said surveillance vehicles to said RF transceiver of said USV wherein said information becomes at least a portion of said data so-collected by said USV.

13. A method according to claim 9 wherein said RF communications means comprises a first RF transceiver for two-way communication with said RF transceiver of said USV and a second RF transceiver for two-way communication with a location that is remote with respect to said USV, said method further comprising the step of operating said first RF transceiver and said second RF transceiver simultaneously.

14. A method according to claim 8 further comprising the steps of:

providing said MAV with data storage means coupled to said RF communications means and to said data collection means of said USV prior to launching said MAV;

transferring said data from said data collection means to said data storage means prior to launching said MAV; and

transmitting with said MAV so-launched.
