    摘要： Systems, devices, and methods including: at least one unmanned aerial vehicle (UAV); at least one battery pack comprising at least one battery; and at least one motor of the at least one UAV, where the at least one battery is configured to transfer energy to the at least one motor; where power from the at least one motor is configured to ascend the at least one UAV to a second altitude when the at least one battery is at or near capacity, and where the second altitude is higher than the first altitude; and where power from the at least one motor is configured to descend the at least one UAV to the first altitude after the Sun has set to conserve energy stored in the at least one battery.

    摘要： Systems, devices, and methods including: at least one unmanned aerial vehicle (UAV); at least one flight control computer (FCC) associated with each UAV, where the FCC controls movement of each UAV; at least one computing device associated with a ground control station; where the at least one FCC maintains a first flight pattern of a respective UAV of the at least one UAV above the ground control station; where the at least one computing device is configured to transmit a transition signal to the at least one FCC to transition the respective UAV of the at least one UAV from the first flight pattern to a second flight pattern in response to a wind speed exceeding a set threshold relative to a flight speed of the respective UAV of the at least one UAV.

    摘要： Systems, devices, and methods for: an unmanned aerial vehicle (UAV); at least one sensorless motor of the UAV, the at least one sensorless motor comprising a set of windings and a rotor; at least one propeller connected to the at least one sensorless motor; a microcontroller in communication with the at least one sensorless motor, wherein the microcontroller is configured to: determine a rotation rate of the at least one propeller; determine a rotation direction of the at least one propeller; provide an output to stop the at least one propeller if at least one of: the determined rotation rate is not a desired rotation rate and the determined rotation direction is not a desired rotation direction; and provide an output to start the at least one propeller if the at least one propeller is stopped at the desired rotation rate and the desired rotation direction.
