Abstract: 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.

Abstract: A method is provided for controlling a signal transmission power of at least one of an unmanned aerial vehicle (“UAV”) or a remote control device. The method includes determining whether a remote control distance between the UAV and the remote control device increases or decreases. The method also includes increasing or maintaining a signal transmission power of at least one of the UAV or the remote control device if the remote control distance increases. The method further includes decreasing or maintaining the signal transmission power of at least one of the UAV or the remote control device if the remote control distance decreases.
