Abstract

A data communication system for unmanned aerial vehicles includes communication links comprising a low-throughput capacity communication link and a high-throughput capacity communication link. The data communication system can also include a base station, to which the unmanned aerial vehicles send aerial data, and from which the unmanned aerial vehicles receive command signals. As the unmanned aerial vehicles perform missions in an open, distant airspace, the unmanned aerial vehicles can gather large volume data such as aerial images or videos. The data communication system allows opportunistic transfer of the gathered aerial data from the unmanned aerial vehicles to the base station when a high-throughput communication link is established. The data communication system allows constant communication between the base station and the unmanned aerial vehicles to send and receive low volume, operation-critical data, such as commands or on-going flight path changes, using a low-throughput communication link.

Claims

1. A system comprising:

an unmanned aerial vehicle;

a base station comprising;

a housing;

a first wireless communication circuit configured to send flight command signals to the unmanned aerial vehicle using a first communication link with a first throughput capacity and a first range; and

a second wireless communication circuit configured to receive aerial data from the unmanned aerial vehicle using a second communication link with a second throughput capacity and a second range, wherein the second throughput capacity is higher than the first throughput capacity and wherein the second range is less than the first range; and

a user interface device configured to generate and send a flight plan or components thereof to the base station for forwarding to the unmanned aerial vehicle,

wherein the unmanned aerial vehicle is configured to cease sending aerial data when travelling outside of the second range; and

wherein the unmanned aerial vehicle is configured to continue receiving flight command signals when travelling outside of the second range and inside of the first range.

2. The system of claim 1, wherein the first communication link has a lower probability of failure than the second communication link.

3. The system of claim 1, wherein the first communication link comprises a 900 MHz band channel and the second communication link comprises a Wi-Fi channel.

4. The system of claim 1, wherein the base station further comprises a third wired or wireless communication circuit configured to send the received aerial data to a remote server.

5. The system of claim 1, wherein the aerial data comprises at least one of:

image data;

video data;

audio data;

telemetry data;

LIDAR data;

3D mapping data; and

gas sensor data;

wherein the aerial data are gathered by the unmanned aerial vehicle.

6. The system of claim 1, wherein the base station comprises manual actuators that command the unmanned aerial vehicle to perform at least one of:

emergency landing;

shutdown propellers;

travelling to a predetermined location;

pausing a mission; and

resuming a paused mission,

wherein one or more manual inputs initiate sending one or more command signals to the unmanned aerial vehicle from the base station through the first communication link.

7. The system of claim 1, wherein the first wireless communication circuit is configured to receive data from the unmanned aerial vehicle using the first communication link.

8. The system of claim 7, wherein the first wireless communication circuit is configured to receive aerial data from the unmanned aerial vehicle using the first communication link.

9. The system of claim 8, wherein the unmanned aerial vehicle is configured to select portions of the aerial data for sending over the first communication link.

10. The system of claim 1, wherein the unmanned aerial vehicle is configured to determine a position of the unmanned aerial vehicle relative to the base station.

11. The system of claim 10, wherein the unmanned aerial vehicle is further configured to send the aerial data to the second wireless communication circuit based at least in part on the position of the unmanned aerial vehicle.

12. The system of claim 1, wherein the unmanned aerial vehicle contains an on-board communication circuit configured to establish the second communication link and send the aerial data to the second wireless communication circuit when the unmanned aerial vehicle is within a threshold range of the second wireless communication circuit.
