초록

A Ground Control System (GCS) is necessary for collision avoidance and flight path optimization of operational Unmanned Aerial Vehicles (UAVs). However, existing GCS can only manage parameters such as flight data and sensor data and do not offer modeling features, making it challenging to safely monitor UAVs in rapidly changing environments. This paper proposes a Digital twin-based Ground Control System (DGCS) for monitoring the status of UAVs. The DGCS allows monitoring the current status of UAVs in a 3D modeled environment using digital twin. The DGCS shows the accuracy of monitoring UAVs in the control system with an average error rate of about 6.75cm. Also, DGCS shows the efficiency of monitoring the status of UAVs at a rate of about 18ms and remotely controlling UAVs at a rate of about 25ms. © 2023 Copyright for this paper by its authors.
