다양한 지역 환경에서의 UTM-K 기반 드론 비행경로 오차 분석

초록

This study examined the generalizability and applicability of a UTM-K-based flight path error analysis methodology using local government drone delivery demonstration data from the Gongju, Yeosu, Ulju, Tongyeong, and Pocheon regions. Drone flight stability was evaluated under various operational environments by transforming GPS-based flight data into the UTM-K orthogonal coordinate system and analyzing route deviations between planned flight paths and actual flight trajectories. A shortest-distance algorithm between the reference route and real-time drone positions was applied to calculate route deviation. The analyzed regions included urban, coastal, island, and mountainous environments, and the regional characteristics of route deviation were compared. The analysis results showed that all drone delivery routes satisfied the flight safety criteria proposed by the Korea Transportation Safety Authority, and the route error rates remained within the allowable range. In particular, the proposed UTM-K-based analysis methodology revealed stable applicability under various regional operational conditions. Therefore, the proposed methodology is expected to help establish flight safety evaluation standards and develop K-UAM-based drone logistics systems for future drone delivery commercialization.
