The uncontrolled distribution and usage of unmanned aerial vehicles (UAVs) in the world, in combination with the risks associated with aircraft, other property, people's lives, privacy, violation of secure territories, and overall security, require the creation of a UAV registration and monitoring system. This work aimed to analyze the current state of the UAV registry in Ukraine, to identify the main weak points, and to develop an architecture for the UAV registration and monitoring system. The following tasks were solved to achieve the goal: analysis of the current state of the UAV registry in Ukraine; identifying the main weaknesses of UAV registration and monitoring in Ukraine and determining the directions for their solutions; development of a UAV registration and monitoring method; development of a model for the registration and monitoring of UAVs using 5G cellular networks; development of software for UAVs' registration and monitoring. As a result of the work, a system was developed that allows registering UAVs when they are turned on and monitoring the current coordinates of the UAVs which are using this system.
