摘要

Aspects of the disclosure provide for a method of forming a communication link between two communication devices using a primary search pattern and a secondary search pattern. A misalignment between a first optical system of a first communication device and a second optical system of a second communication device is detected. The first optical system is rotated according to the primary search pattern, and the second optical system according to the secondary search pattern. At the second communication device, a set of frames is captured. Then, it is determined whether a beacon beam transmitted from the first communication device is detected in the one or more of the captured frames. When it is determined that the beacon beam is detected, the communication link is formed between the first communication device and the second communication device.

說明書

FIG. 5A illustrates an example aircraft 500a, such as, for example, an unmanned aerial vehicle (UAV) or an aircraft without a human pilot onboard. The UAV may be autonomous, remotely piloted, or both. FIG. 5B illustrates an example communication balloon 500b that includes a balloon 502, an equipment box 504, and solar panels 506. The equipment box 504 may also include batteries to store power and the communication device 200 to communicate with other devices (e.g., other HAPs 500, satellites 400, stationary terminals 300). The solar panels 506 may power the equipment box 504.
