    摘要： Systems and methods for detecting an unmanned aerial vehicle (UAV). Network access (for example, to the Internet) may be provided by detecting a UAV and fixing one or more beams from one or more ground terminals to the UAV. In one embodiment, the detection of a UAV includes forming and pointing beams from a ground terminal and ground gateways toward the UAV. The ground terminal may be configured to autonomously steer its antenna beam during initial installation to detect the reference signal from a UAV. In one variant, the ground terminals are steered to more finely track the position of the UAV based on a signal quality metric such as received signal strength and the UAV real-time position location coordinates. In one embodiment, the ground terminal antenna is initially manually pointed toward the UAV, and thereafter allowed to automatically steer to track the position of the UAV. In another embodiment the UAV antenna is steered toward a ground terminal using signal quality received from the ground terminal and real-time position coordinates and orientation of the UAV.

    摘要： Systems and methods for mitigating the effects of atmospheric conditions such as rain, fog, cloud in a broadband access system using drone/UAVs. In one embodiment, terminal and drone radio and transmission medium fixture sub-systems comprise multiple transmission media. In one embodiment, in response to changes in atmospheric conditions the drone radio sub-system switches transmission medium to reduce the effects of atmospheric conditions. In another embodiment, the terminal and drone radio sub-systems equalize the data rates among terminals in response to changes in atmospheric conditions observed by different terminals. In another embodiment, the drone radio sub-system adjusts the transmit power on the downlink to different terminal according to fading due to atmospheric conditions on each link.

    摘要： The present disclosure describes the system and methods for providing broadband internet access to homes and enterprises using a network of aerial platforms such as drones/UAVs/balloons. The drone communication system is composed of an antenna sub-system, a radio sub-system and a data switching sub-system. Drones form and point beams toward ground terminals in different areas in a space division multiple access scheme. Ground terminals are composed of an antenna sub-system and a radio sub-system. Ground terminals search for the drone from which they receive the strongest signals. Drone and ground terminals comprise of methods and systems to calibrate receive and transmit antenna elements. Drone radio sub-system keeps track of the drone's position and orientation changes and adjust drone's antenna beam accordingly to point to the same location on the ground as the drone moves. Depending on the changes in drone's position and orientation, the drone radio sub-system may switch the antenna aperture and/or the antenna fixture that is used to form a beam toward a specific ground terminal. Drones communicate with the terminals using a space and time division multiple access scheme.
