Abstract: A location tracking system has been developed in order to tracks the location of a moving terminal and provide various tracking services based on the location. Methods/Statistical analysis: This paper presents a method to find a target using UAVs in LoRa communication environment. The proposed method proposes a UAV flight path where the target signal can be found without blind spots. The flight path was changed by using the intensity of the transmitted signal during the flight using the variation of the signal strength. Findings: We verified the proposed method by simulation and confirmed that it takes a long time to track the target, although the efficiency of the 3 flights is high. It is best to fly three UAVs to reduce time to find target and increase efficiency when the time is a critical factor. The LoRa communication lowers the production cost and makes it possible to construct the system with low cost. Improvements/Applications: The proposed method provides the location-based service collecting location target information on the terminal and provides various services such as route guidance, prevention of crime, or finding a missing child.
