Systems and methods to iteratively map-and-approach an urban area using flying drones. Each of the iterations includes drones flying over the urban area using terrain-following techniques in conjunction with a 3D model that was updated in previous iterations, in which flight paths are defined in conjunction with the 3D model so as to stay away of ground-related features appearing in the 3D model. As the iteration processes progresses, the model becomes increasingly accurate with additional details about the ground related features, thereby allowing the drones to safely approach the ground related features. The iterations converge into a low altitude flight over roads in the urban area, as flying at low altitudes over roads allows the drones to gather information of interest about buildings, infrastructure and assets, in which such information would be difficult to obtain using other techniques. Close proximity to ground related features allows drone delivery functions as well.

A ground power unit provides electrical energy for aircraft and a method maintains and operates the ground power unit. The ground power unit includes a base frame, a cable system formed in the base frame, at least one rectifier module for converting an input alternating voltage applied to a rectifier module input side into an intermediate direct voltage output at a rectifier module output side, wherein the rectifier module output side is coupled to an intermediate circuit conductor and at least one inverter module for converting the intermediate direct voltage applied to an inverter module input side into an output alternating current output at an inverter module output side, wherein the inverter module input side is coupled to an intermediate circuit conductor. The rectifier module and the inverter module are each realized as structurally-independent units, which can be replaced individually and independently of the base frame.

The invention is intended for the organization of an automated process for spraying of liquid means of chemical treatment from unmanned vehicles, for example, in precise farming systems. The invention provides the use of a replaceable, marked and hermetically sealed liquid subsystem with integrated pumping chambers in a spraying device together with an integrated self-diagnosis system allowing to ensure personnel safety and the accounting of the resources of main components of the spraying device. All this in combination enables to create fully automated spraying systems.

The present invention discloses an integrated airport design. The runways are designed in an elevated curved shape. The middles of landing runways and take-off runways are designed as an overhead parking apron, and the terminal building is below the runways. Therefore, the usable area of the whole airport is increased. The length of each elevated curved runway is lengthened comparing to the traditional straight runway within the same area. In addition, the downhill take-off runway can enhance take-off operation and reduce the fuel consumption. Thus, the existing land resources can be used to the maximum extent.
