Structure Design for Unmanned Aircraft Traffic Management System

The application of the Unmanned Aircraft System (UAS) in various fields has been attracting attention, and the development of a service utilizing UAS has been proceeding. With the increase in the number of Unmanned Aerial Vehicles (UAVs) and the increase in the scale of UAS networks, the role of management system for safety of UAS in the public airspace is becoming more important. Due to this safety issue of UAS, many project are currently underway to manage UAS traffic in various countries. This UAV traffic management system is called UAS Traffic Management (UTM) system, and Korea is also conducting a national project to build Korean UTM system. In this paper, we design the structure for UTM system implementation and define required functions for security and safety. In addition, we define the message to operate essential functions in the proposed UTM structure and design message flow between entities. Finally, we show the demonstration scenario that has been verified by applying our designed UTM system to real environment.
