Analysis of Duplicate UTM Services and Their Context of Influence on Airspace Capacity

This research paper focuses on comparing the definitions and duplication of different Unmanned Aircraft Traffic Management (UTM) services across different concepts around the world. The paper presents a comprehensive overview of the definitions of each UTM service and analyses how these concepts differ or are similar across regions and international contexts. In addition to the uniqueness of UTM services from the point of view of definitions, the paper tries to determine their influence on capacity from the point of view of defined parameters that emerged from the search of available publications. Based on the mentioned analysis, there were identified 114 UTM services, from which only 44 are unique.
