Data communication systems and methods

摘要

The present invention provides systems and methods for improved data communication between communication terminals such as a base station and an unmanned aerial vehicle. In some instances, the systems and methods described herein provide robust transmission uplink data such as control data and wideband transmission of downlink data such as image data or other sensor data, while avoiding interference between the uplink data transmission and the downlink transmission.

主权项

1. A remote controller for controlling an unmanned aerial vehicle (UAV), comprising:
an uplink transmitter configured to transmit uplink data to the UAV, the uplink data including (1) control data for controlling operations of the UAV, and (2) synchronization information useful for synchronizing transmission of the uplink data or downlink data between the UAV and the remote controller; and a downlink receiver configured to (1) measure one or more quality characteristics of each of a plurality of working frequency channels to provide measured quality characteristics; (2) select a working frequency channel from the plurality of working frequency channels based on the measured quality characteristics; and (3) receive, using the selected working frequency channel, the downlink data provided by the UAV.
