Abstract

A global communication system includes a mobile portion; a phased-array antenna attached to the mobile portion; an actuator to move the antenna in one direction to face a satellite; a transceiver to communicate with the satellite; and a processor controlling the actuator to optimize communication from the transceiver.

Claims (28)

1. A global communication system, comprising:

a mobile portion adapted to move in a first direction;

a phased-array antenna attached to the mobile portion;

a motor actuator to move the antenna in one direction to face a satellite, wherein the mobile portion and the motor actuator in combination position the antenna to receive signals from the satellite;

a first transceiver to communicate with the satellite; and

a processor controlling the motor actuator to optimize communication from the first transceiver.

2. The system of claim 1 , wherein the mobile portion comprises a backpack portion, a vehicle portion, a moveable tent portion, a cell phone, a personal communicator, a hat, a watch, skin, clothing, or a wearable portion.

3. The system of claim 1 , wherein the actuator comprises a motor, a hydraulic actuator, or an inflatable chamber.

4. The system of claim 1 , wherein the antenna comprises a substrate, comprising a solar panel above, under, or planarly adjacent the antenna.

5. The system of claim 1 , wherein the phase-array antenna comprises a transparent material.

6. The system of claim 1 , comprising a plastic cover, a rain cover, or a water-repellant material to protect said antenna.

7. The system of claim 1 , comprising a local area network to allow local devices to access the Internet.

8. The system of claim 7 , wherein the local area network comprises a local area network (LAN) or personal area network (PAN).

9. The system of claim 1 , comprising a lens or a reflector to focus energy on the antenna.

10. The system of claim 1 , comprising a second transceiver to communicate with a second satellite, and channel bonding code to increase communication speed with two satellites.

11. The system of claim 1 , comprising code to bond communication channels together to increase communication speed.

12. The system of claim 1 , comprising a terrestrial transceiver to communicate with a cellular base, and channel bonding code to increase communication speed using a combination of terrestrial and satellite communication.

13. The system of claim 1 wherein the antenna is mounted to a roof of a vehicle, wherein the actuator mechanically moves the phased array antenna in one dimension and communicate with a satellite constellation that emits or receives radio frequency (RF) signals and has a repeating ground track in a first direction, the antenna including a plurality of antenna elements distributed in a plurality of M columns oriented in the first direction and a plurality of N rows extending in a second direction normal to the first direction, and a plurality of phase shifters aligned for phase offsets between antenna elements in the first direction; wherein the antenna enhances gain in a second direction of radio frequency signals received by and emitted from the phased array antenna.

14. The system of claim 1 , comprising a terrestrial transceiver and a second transceiver to communicate with a second satellite, and channel bonding code to increase communication speed with a plurality of satellites and terrestrial communication.

15. The system of claim 1 , comprising an inflator coupled to the antenna to form an inflatable antenna.

16. The system of claim 1 , wherein the mobile portion comprises an autonomous vehicle, a robot, a drone.

17. The system of claim 1 , comprising a mesh network transceiver coupled to the processor.

18. A method for mobile communication, comprising:

securing a phased-array antenna to a mobile portion;

moving the antenna in one direction with a motorized actuator to face a satellite, wherein the mobile portion and the motor actuator in combination position the antenna to receive signals from the satellite;

communicate with the satellite and controlling the actuator to optimize communication from one or more transceivers.

19. The method of claim 18 , wherein the mobile portion comprises a backpack portion, a vehicle portion, a moveable tent portion, a hat, a cell phone, a personal communicator, a watch, a skin, clothing, or a wearable portion.

20. The method of claim 18 , comprising mounting the antenna to a roof of a vehicle, wherein the actuator mechanically moves the phased array antenna in one dimension and communicate with a satellite constellation that emits or receives radio frequency (RF) signals and has a repeating ground track in a first direction, further comprising identifying a repeating ground track of the satellite constellation in a first direction; orienting a phased array antenna in the first direction, the antenna including a plurality of antenna elements distributed in a plurality of M columns oriented in the first direction and a plurality of N rows extending in a second direction normal to the first direction, and a plurality of phase shifters aligned for phase offsets between antenna elements in the first direction; enhancing gain in the second direction of radio frequency signals received by and emitted from the phased array antenna; and receiving and/or emitting RF signals between the satellite constellation and the antenna.
