Abstract: The present disclosure relates to a method of navigating an unmanned aerial vehicle (UAV). The method includes the steps of controlling a flight path of the UAV by a remote operator, obtaining a recognized air picture of an observation space surrounding the UAV, assigning one of a plurality of threat levels to each of the aerial vehicles, the threat levels comprising a resolution advisory level and an automatic avoidance level and continuously automatically determining viable avoidance trajectories for the UAV). If an aerial vehicles is assigned the resolution advisory level, a message is provided to a remote operator including a first proposed viable avoidance trajectory. If an aerial vehicles is assigned the automatic avoidance level, control signals are provided to an on-board flight controller instructing the vehicle to follow a flight path corresponding to a second proposed viable avoidance trajectory.

Abstract: The present disclosure relates to a method of obtaining a recognized air picture of an observation space surrounding an automated aerial vehicle. The method comprises the steps of receiving first signals of first cooperative systems of aerial vehicles within the observation space using a first receiver on board the automated aerial vehicle and receiving second signals of second cooperative systems of aerial vehicles within the observation space using a second receiver on board the automated aerial vehicle. The first receiver and the second receiver are adapted to receive signals according to different protocols. The first signals and the second signals are processed using a processor on board the automated aerial vehicle to obtain tracking information with respect to the aerial vehicles within the observation space.

Abstract: Provided is an aircraft having a spherical body which generates buoyancy or which may generate buoyancy when filled with gas, wherein the aircraft further comprises four actuation units arranged on the surface of the body for movement of the aircraft in a translation and/or rotation through air, and at least one camera arranged on or in the surface of the body. Further provided is a method for providing optical information to a person in the environment of a flying aircraft, a method for providing optical information about an object and/or surveying of an object, a method for transmission of acoustic information and a method for observing or tracking an object.
