(FY2017-FY2019) FY2018 Annual Report

For this R&D effort, firstly, based on the basic operation management concept formulated last year, the method for detecting and eliminating conflicts in flight plan management and movement management was embodied. In particular, as a collision avoidance method between drones, in addition to the rule-based method, we developed a method that can cope with the intersection of many drones by route optimization algorithm. With regard to safe and efficient use of radio waves (radio wave management), the premise and basic ideas regarding the principal and responsibility are organized, and the necessary functions and allocation of functions to system components for each communication system were defined. Regarding security measures, we considered possible risks and security locations for information systems. Furthermore, in order to examine the third-party certification method in security that should be applied to the operation management system, the survey of existing international certification standards was conducted, and the application method was examined.

Secondly, interface information in the system architecture (basic specifications) formulated last year was managed and the API connection between system components was supported. In addition, we conducted a basic study on advanced UTM concepts such as approach information for manned aircraft and Remote ID. In addition, and We evaluated the impact on airspace from the viewpoint of flight safety due to failure of each system and preventing the serious impediment of the operation of unmanned aircraft and the lowering of the utilization efficiency of airspace using safety analysis methods such as FTA and FMEA, with a view to basic examination of the advanced concept, in the case of different collision detection and avoidance function sharing during flight.

Thirdly, the basic functions of UTM simulator (FIMS, UASSP, UAS simulator and analysis function) was completed. Hence, it has become possible to carry a large scale UTM operation simulation along the developed model case. Moreover, the wireless network simulator developed in 2018 was extended, the communication interference calculation function between unmanned vehicles and terrain data reading function were developed. Next, the UTM concept was evaluated using the UTM simulator. The simulation result showed that the UTM concept was appropriate. However, it was cleared that there were some problems with safety/scalability, so some algorithms to solve these problems were developed.

Lastly, to conduct the above tasks, the UTM System Development Steering Committee which consists of various stakeholders was operated and formed the necessary consensus. Prior to that, we held the working group meetings consisting of system development teams and executed technical coordination. Three committee meetings, and 8 working group meetings were conducted this year.
