  • Publication number: 20200302806
    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.
