Opening the airspace of cities for common use for drones brings not only new possibilities but also new duties. The entity that is going to take responsibility for that mission are city authorities. There is a rapid growth of a number of companies who are ready to offer services based on Unmanned Aircrafts in the area of city airspace. The authorities are forced to inventory and give permissions for using this space on stated terms. It brings the necessity of verification if the subject satisfies conditions of using the airspace and automatization of giving permission. U-Space Management System will support authorities in managing the airspace during every step – from inventorying in form of 3D maps, charting flight paths for drones, demarcating forbidden and available for temporary use areas. It will also allow for automatic processing of permit application and will give the preview of the usage and the traffic in the airspace, including different heights.
