  • Publication number: 20210263537
    Abstract: Unmanned aerial vehicle (UAV) systems, including autonomous UAV operational containment systems, and associated systems, devices, and methods are disclosed herein. In one embodiment, a UAV operational containment system includes a cloud-based flight manager, a control tower, and navigation beacons. The control tower is configured for direct communication with the flight manager. Each navigation beacon is configured for communication with the control tower and for communication with the flight manager via the control tower. The system can further include a UAV having a first localization system and a second localization system. Each localization system is configured to determine a position of the UAV independent of the other localization system. In some embodiments, the system is configured to contain the UAV within an operational envelope defined for the site of operation and/or to execute a pre-defined emergency flight plan in the event of an in-flight emergency.

  • Publication number: 20210264799
    Abstract: Unmanned aerial vehicles (UAVs), including multi-processor UAVs with secured parameters, and associated systems, devices, and methods are disclosed herein. In one embodiment, a UAV includes a flight controller configured to control flight operations of the UAV based at least in part on system parameters provided to the UAV. The UAV can additionally include an oversight processor configured to (i) monitor operations of the flight controller and (ii) intercede when the oversight processor determines the flight controller is operating in violation of the system parameters. In some embodiments, the system parameters are secured (e.g., digitally signed and/or encrypted) and provided to the UAV. In these and other embodiments, the UAV is configured to verify the secure systems parameters and/or to autonomously execute a flight plan after verifying the system parameters. In some embodiments, the system parameters define an operational envelope specifying airspace to which autonomous flight of the UAV is constrained.
