Hover Location Selection and Flight Path Optimization for UAV for Localization Applications

A typical application of drones is to locate ground targets. This article considers that during the flight of the drone, the drone hovers at a specific location and broadcasts a beacon signal. If the ground node and the drone are hovering When the distance of the parking position meets the communication range, the beacon signal of the drone can be monitored.When the ground node monitors the beacon signal of 3 or more different hovering positions, it can use the multilateral positioning method to locate itself. The article mainly solves the problem of how to choose the hover position and how to optimize the flight path of the drone when the hover position is given. The flight path of the aircraft proves that the paths proposed under the two hovering schemes are the shortest loops. Through simulation experiments, it is verified that the proposed scheme can achieve complete coverage of the area to be covered, so that any ground node can achieve positioning; and the The solution can improve the positioning accura
