    摘要： A method for communicating ground terminal-to-unmanned aerial vehicle (GT-UAV) data one or more times to an unmanned aerial vehicle (UAV) from a ground terminal includes receiving the GT-UAV data over a wireless channel, transmitting UAV image data to the ground terminal over the wireless channel, determining whether the received GT-UAV data is transmitted according to an Acknowledgment (ACK) protocol, and transmitting an acknowledgment signal over the wireless channel to the ground terminal in response to the received GT-UAV data being determined to be transmitted according to the ACK protocol.

    摘要： A control function configuration method includes broadcasting a control function message in a control system through a narrow-band communication network, and receiving a function-configured notification message sent by a target secondary control device in the control system through the narrow-band communication network. The function-configured notification message indicates that a control function of the target secondary control device has been configured to be a target control function. The method further includes broadcasting a function-configured status message in the control system through the narrow-band communication network. The function-configured status message indicates that the control function of the target secondary control device has been configured to be the target control function.

    摘要： A method for monitoring an unmanned aerial vehicle (UAV) includes a processor generating a datagram based on monitoring data for a UAV-detector communication between the UAV and one or more detectors. The monitoring data indicates at least one of a location of the UAV or a location of a control station in communication with the UAV. The method further includes the processor encrypting working data for a UAV-control station communication between the UAV and the control station using an encryption key known to the control station but now known to the one or more detectors, and a transmitter transmitting the datagram along with encrypted working data. The datagram is to be received by the one or more detectors and the encrypted working data is to be received and deciphered by the control station using the encryption key.

    摘要： The present disclosure provides a method and apparatus for flight control and an aerial vehicle thereof. The flight control used in an aerial vehicle includes the following steps: identifying a reference object in a flight environment; obtaining a distance between the aerial vehicle and the reference object; acquiring a flight strategy corresponding to the distance based on a correspondence between the distance between the aerial vehicle and the reference object and the flight strategy; and, controlling the aerial vehicle to fly based on the flight strategy. The method and apparatus for flight control and an aerial vehicle thereof can be used to perform effective obstacle avoidance.

    摘要： A secure communication method comprising obtaining a secret code generated in response to a first communication device being paired with a second communication device, obtaining a prestored product key, generating a module key based on the secret code and the product key, randomly generating a session key, obtaining a key sequence number, auto-incrementing the key sequence number, setting a sending sequence number with an initial value of zero, generating a key frame by performing a computation on the session key and a verification authentication code of the session key using the module key, sending a data packet including the key frame, the key sequence number, the sending sequence number, and a data type to the second communication device. The data type indicates that the data packet is a key data packet.
